GregoryAbstractWe investigate the stability of the electroweak vacuum in metric-affine gravity in which the Standard Model Higgs boson can be non-minimally coupled to both the Ricci scalar and the Holst invariant. We find that vacuum stability is improved in this framework across a wide range of model parameters.Data availabilityNo data was used for the research described in the article.1IntroductionIt is well known that the potential of the Higgs boson in the Standard Model (SM) is deeper at high energies than in the electroweak vacuum permitting its decay through quantum tunneling [1–4]. Although this does not invalidate the SM, the electroweak vacuum is predicted to be metastable in the absence of contributions from UV physics [5–13].Coleman and De Luccia [14] were the first to delve into the matter of gravitational effects on vacuum decay. Subsequently, multiple studies of gravitational corrections have been performed [15–23], along with discussions about the impact of black holes on the amplification or reduction of the vacuum decay rate [24–40].In this letter, we extend the calculation of gravitational corrections to vacuum decay in the context of metric-affine gravity. There, in contrast to general relativity, the connection is taken to be an independent variable without the usual symmetries of the Levi-Civita one. As a result, the Riemann tensor does not possess the symmetries it has in the metric case, and thus the gravitational action should be extended by including an additional scalar curvature invariant - the Holst invariant. This term commonly appears in Loop Quantum Gravity [41] and has been studied in various branches of high energy physics, such as black hole thermodynamics [42,43]. Lately, its significance in inflationary cosmology [44–49], and high energy physics phenomenology [50–54], has garnered a great deal of attention.2The gravitational actionMetric-affine theories of gravity treat the metric tensor gμν and the connection Γλμν as independent variables. This should be contrasted with the usual metric gravity that uses the Levi-Civita connection {μνλ}, which is completely determined by the metric. It is useful to decompose the connection Γλμν as(1)Γλμν≡{μνλ}+Cλμν, where Cλμν is dubbed the distortion tensor. The Riemann tensor Rμνρσ is constructed from the connection Γ in the usual way and one can form two scalars that are linear on it. These are the Ricci scalar and the Holst invariant [55,56](2)R≡Rμνμν,R˜≡12ϵμνρσRμνρσ, where g is the determinant of the metric tensor and ϵμνρσ is the totally antisymmetric tensor. In metric gravity, the Holst invariant vanishes identically due to the symmetries of the Riemann tensor.The most general action linear in the Riemann tensor and containing terms of at most dimension 4 has the form11Natural units with c=ħ=1 are used throughout this paper.(3)S=∫d4x−g[R2f(h)+R˜2f˜(h)−12(∂h)2−V(h)], where V(h) is the Higgs potential,(4)f(h)=1/κ+ξh2,f˜(h)=β/κ+ξ˜h2, are non-minimal couplings, β, ξ and ξ˜ are constant couplings, and κ=1/MPl2. The function 1/f˜(h) can be thought of as a field-dependent Barbero-Immirzi parameter [56,57]. We will first work out the formalism without assuming a specific functional form of f, f˜, and V and suppress their arguments for notational brevity.In addition to the Ricci and Holst terms, metric-affine gravity permits the construction of 20 additional scalars with mass dimension 2 from torsion Tρμν≡2Γρ[μν] and non-metricity Qρμν≡∇ρgμν [58,59]. Although such terms are not considered in this work, our perturbative results can be straightforwardly extended to include them as will be explained below. We will also neglect couplings between the connection and fermions as they will only generate Planck-suppressed four-fermion and higher-order scalar-fermion interactions [47,51,53,60] and do not affect the leading order corrections to vacuum stability.We remark that the action (3) also appears in Einstein-Cartan gravity. A crucial distinction with the current case is that the Einstein-Cartan connection is decomposed using the Levi-Civita connection and torsion and, unlike in metric-affine gravity, the non-metricity is taken to be zero. Nevertheless, as we will show below, the metric-affine framework contains both the metric and Palatini formulations as limiting cases and the non-metricity may be taken to zero without loss of generality.In order to study bounce solutions, we construct the Euclidean action (3) by analytically continuing the Lorentzian signature (−,+,+,+) to the Euclidean one (+,+,+,+). Then, to bring the action to a more conventional form, we will first integrate out the connection. To this aim, we will express the Ricci scalar and the Holst invariant in terms of the metric Ricci scalar R[g] and the distortion tensor,(5a)R=R+DμCμνν−DνCμμν+CμμλCλνν−CμνλCλμν,(5b)R˜=ϵμνρσ(DμCρνσ+CρμλCλνσ), where D denotes the covariant derivative of the Levi-Civita connection. Substituting Eq. (5a) and (5b) into the action (3), yields22Although the Holst term picks up an imaginary unit when continuing to Euclidean space, analogously to the CP violating topological term in Yang-Mills theory (e.g., see Ref. [61]), its effect is negated due to the dependence of ϵμνρσϵμνρσ=sign(g)4! on the sign of the metric determinant.(6)SE=∫d4xg[−R2f+12(∂h)2+V−f2(DμCμνν−DνCμμν+CμμλCλνν−CμνλCλμν)−if˜2ϵμνρσ(DμCρνσ+CρμλCλνσ)]. The distortion tensor obeys an algebraic non-homogeneous linear equation of motion. Thus, in order to integrate it out in full generality, it is sufficient to find a particular solution to this equation [47]. Such a solution is given by [49](7)Cμνρ=12(gνμ∂ρX−gνρ∂μX−iϵμνρσ∂σY), where(8)f=eXcos⁡(Y),f˜=eXsin⁡(Y). This solution is metric compatible, i.e., Qρμν=−2C(ν|ρ|μ)=0, and has torsion Tρνμ=2Cρ[νμ]. So, the theory is dynamically equivalent to the Einstein-Cartan theory. On the other hand, the particular solution (7) is not the general one because of the projective symmetry of the action, Cρνμ→Cρνμ+gρμAν, which can be used to induce the non-metricity Qρμν=−2gμνAρ. In particular, the Palatini limit with f˜=0 is obtained by choosing Aν=∂νX/2.Substituting (7) in the action (6) gives(9)SE=∫d4xg[−R2f+12K(∂h)2+V], where the contribution of the independent connection is now fully captured by the kinetic function33The primes denote differentiation with respect to the argument of the function, that is, depending on the context, with respect to h or r.(10)K=1+32ff˜′2−2f′f˜f˜′−ff′2f2+f˜2. Note that the action (9) does not depend on the sign of f˜.For specific combinations of the involved functions, the general metric-affine theory interpolates continuously between the metric (K=1) and the Palatini (K=1−(3/2)f′2/f) theories. In accordance with Ref. [44], we find that these scenarios correspond to(11a)f˜=cf2−14c,(metric)(11b)f˜=cf,(Palatini) with c a constant. As an important case, the metric formulation can be obtained in the limit in which the constant part of f˜ is large. More specifically, without loss of generality we can consider f˜(h)=β/κ+f˜1(h), where f˜1, f are arbitrary functions of h. If |β|/κ≫f˜1,f, then(12)K=1−3κβf′f˜′+O(κβ)2, and thus the metric-affine theory approaches the purely metric theory when |β|→∞. With f, f˜ given by (4), the Palatini formulation corresponds to β=ξ˜/ξ, of which β=ξ˜=0 is only a special case. Consequently, as β ranges from −∞→ξ˜/ξ→∞, the metric formulation is continuously deformed to the Palatini one and back.3Corrections to vacuum decay in metric-affine gravityTo compute the minimal bounce action, we will look for O(4) symmetric solutions [62], with the line element ds2=dr2+ρ2dΩ32, where dΩ32 denotes the line element of the unit 3-sphere and the Higgs field depends only on the radial coordinate r, i.e. h=h(r). In this background, the metric Ricci scalar reads R=6(1−ρρ″−ρ′2)/ρ2 and the Euclidean action can be recast as(13)SE=2π2∫drρ3[3fρρ″+ρ′2−1ρ2+12Kh′2+V]. The bounce solution is determined by the following equations of motion44The ρ equations of motion follow from the rr component of the Einstein equations, but can also be derived by varying the action (13).(14a)ρ′2=1+ρ23f(12Kh′2−V−3ρ′ρf′h′),(14b)h″=−3ρ′ρh′+1K(−12K′h′2+V′−R2f′). To obtain the bounce action, we will adopt the perturbative method proposed in Ref. [15] and look for solutions as a series in κ, i.e.(15a)h(r)=h0(r)+κh1(r)+O(κ2),(15b)ρ(r)=r+κρ1(r)+κ2ρ2(r)+O(κ3), This approach is suitable when the gravitational corrections are relatively small, and, as we will demonstrate, this technique is adequate for elucidating the differences that emerge due to the inclusion of the Holst invariant. In a similar vein, the bounce action (13) can be expanded as(16)SE=S0+κS1+O(κ2).The leading order solution55See also [63] for exact solutions for vacuum decay in Higgs-like unbounded potentials. h0(r) of (14) is the so-called Fubini instanton [64,65](17)h0(r)=2|λ|2μ1+μ2r2, with μ being an arbitrary scale of the bounce. It solves the equation of motion in the absence of gravity (ρ0=r) and with V(h)=λh4/4 assuming that the Higgs quartic coupling λ is constant and negative. The leading order contribution to the action (13) is(18)S0=2π2∫drr3(h0′22+V(h0))=8π23|λ|, and gives the bounce action in the absence of gravity. To obtain the gravitationally corrected action one must account for the running of λ [17,19]. We will evaluate λ at the scale of the bounce μ and then minimize the action with respect to μ. The running of λ is computed at a 3-loop level [11] with the relevant parameters taken from [66].Evaluating the gravitational correction S1 relies on the specific form of f and f˜, for which we will assume the form (4) when needed. We will assume that the leading order gravitational corrections to the kinetic function (10) can be expressed as(19)K=1+κK1h2+O(κ2), where K1 is a dimensionless constant. Indeed, with f and f˜ given by (4), we have that(20)K1≡−6ξ2+2βξξ˜−ξ˜21+β2. Note that for large β we recover Eq. (12). At order O(κ), the equation of motion (14a) is(21)ρ1′=16r2(12h0′2−V(h0)−3f′(h0)h0′), independently of the shape of f˜. For the Fubini bounce (17), it is solved by(22)ρ1=1+6ξ3|λ|/μ2(rμ2r2−1(μ2r2+1)2+μ−1arctan(μr)). Knowing ρ1 is sufficient to compute the O(κ) correction S1 to the action. We checked explicitly that the dependence on h1 can be eliminated by the h0 equations of motion and partial integration. This is a general result, however, because h0 minimizes the action in the absence of gravity and thus S0[h0+κh1]=S0[h0]+O(κ2) [19]. In all, we obtain that(23)S1=32π2μ245λ2(μ)((1+6ξ)2+6K1)=32π2μ245λ2(μ)((1+6ξ)2−36ξ2+2βξξ˜−ξ˜21+β2), where K1 encodes the modifications resulting from an independent connection, i.e., setting K1=0 recovers the metric case.The gravitational correction (23) can be negative for certain values of model parameters. If this happens, then the action cannot be minimized with respect to μ and the adopted perturbative approach is not applicable. However, by minimizing S1 with respect to ξ, it is straightforward to show that S1 is always positive when(24)βξ˜≥1/12. Otherwise, the positivity of the gravitational correction S1 can be achieved only in certain regions of the parameter space. Two special cases warrant being considered more closely:1.ξ˜=0: A minimally coupled Holst term f˜(h)=β/κ is probably the simplest scenario. The region allowed by the positivity of S1 is(25)|ξ+16+16β2|≥1+β26β2. For β≪1, this gives ξ≤−1/(3β2) or ξ≥−1/12, while, when β≫1, only a narrow region around the conformal coupling ξ=−1/6 is forbidden, that is, |ξ+1/6|≥1/(6β).2.β=0: In this case, the contribution from the Holst term(26)S1=32π2μ245λ2(μ)(1+12ξ+36ξ˜2), is always positive and will thus always improve the stability of the SM vacuum when compared to the Palatini case. This special case is depicted in the middle panel of Fig. 1 However, as in the Palatini limit, the positivity of S1 implies a strict lower bound(27)ξ≥−1/12−3ξ˜2.The minimal bounce action is shown in Fig. 1 with the running of λ computed at the 3-loop level [11]. It shows that the metric limit β→∞ is realized quite well already for |β|=6 when ξ˜≈0. For ξ˜≫1, we see that the bounce action is typically enhanced when β and ξ have the opposite signs, thus improving the stability of the vacuum. Additionally, in comparison to the metric case, the stability is improved when |ξ|<|ξ˜|. In all depicted cases, the regions in which S1<0 can be observed: When β=6, this region exists only for the ξ˜=0 line and is contained in a narrow range around ξ=−37/216. In the β=−6 case, a parameter region with S1<0 can be observed for every ξ˜. The disallowed ξ range varies with ξ˜. Since the theory is independent of the sign of f˜, then the β=6 panel covers the β=−6 case with ξ˜∈[−100,0] and vice versa.Finally, it is important to point out that, as in the action (9), the contributions from mass dimension 2 terms constructed from torsion and non-metricity that can appear in metric-affine gravity can be reduced to a non-canonical kinetic term in a metric theory [59]. This implies that our results can be straightforwardly extended to include corrections to vacuum stability from such terms by computing their contribution to the small κ expansion (19).4ConclusionsWe analyzed the stability of the electroweak vacuum in metric-affine gravity, where the Higgs boson is expected to have an additional non-minimal coupling to the Holst invariant. This scenario can be reformulated in terms of an equivalent metric theory with a non-canonical kinetic term, where the gravitational corrections to the bounce action can be studied with established perturbative methods. Our results show that the stability of the electroweak vacuum in metric-affine gravity is improved across a wide range of model parameters.A non-minimally coupled Holst term provides a class of models that continuously connects metric and Palatini gravity. We find that the limiting case of Palatini gravity displays the mildest improvement to vacuum stability.

The systematic uncertainties are minimised since the measurements are recorded by the same experimental apparatus (ALICE). The distributions for p Pb and Pb Pb collisions are determined as a function of the centrality of the collisions, while results from pp collisions are reported for inelastic events with at least one charged particle at midrapidity. The charged-particle pseudorapidity densities are, under simple and robust assumptions, transformed to charged-particle rapidity densities. This allows for the calculation and the presentation of the evolution of the width of the rapidity distributions and of a lower bound on the Bjorken energy density, as a function of the number of participants in all three collision systems. We find a decreasing width of the particle production, and roughly a smooth ten fold increase in the energy density, as the system size grows, which is consistent with a gradually higher dense phase of matter.", "One of the leading issues in quantum field theory and cosmology is the mismatch between the observed and calculated values for the cosmological constant in Einstein's field equations of up to 120 orders of magnitude. In this paper, we discuss new methods to potentially bridge this chasm using the generalized uncertainty principle (GUP). We find that if quantum gravity GUP models are the solution to this puzzle, then it may require the gravitationally modified position operator undergoes a parity transformation at high energies.", "This letter reports measurements which characterize the underlying event associated with hard scatterings at mid-pseudorapidity ( |η|<0.8) in pp, p–Pb and Pb–Pb collisions at centre-of-mass energy per nucleon pair, sNN=5.02 TeV. The measurements are performed with ALICE at the LHC. Different multiplicity classes are defined based on the event activity measured at forward rapidities. The hard scatterings are identified by the leading particle defined as the charged particle with the largest transverse momentum ( pT) in the collision and having 8 <pT<15 GeV/ c. The pT spectra of associated particles (0.5 ≤pT<6 GeV/ c) are measured in different azimuthal regions defined with respect to the leading particle direction: toward, transverse, and away. The associated charged particle yields in the transverse region are subtracted from those of the away and toward regions. The remaining jet-like yields are reported as a function of the multiplicity measured in the transverse region. The measurements show a suppression of the jet-like yield in the away region and an enhancement of high- pT associated particles in the toward region in central Pb–Pb collisions, as compared to minimum-bias pp collisions. These observations are consistent with previous measurements that used two-particle correlations, and with an interpretation in terms of parton energy loss in a high-density quark gluon plasma. These yield modifications vanish in peripheral Pb–Pb collisions and are not observed in either high-multiplicity pp or p–Pb collisions.", + "We investigate the stability of the electroweak vacuum in metric-affine gravity in which the Standard Model Higgs boson can be non-minimally coupled to both the Ricci scalar and the Holst invariant.
