Higgs-field gravity

Induced gravity inflation in the standard model of particle physics

“…In this paper, we want to discuss some early Universe consequences of a theory of gravity coupled to the isovectorial Higgs field of the standard model, which is proved to produce a type of Yukawa gravitational interaction [23,24,25], and which breaks down to give rise to both some boson and fermion masses and the Newton's constant. Since the symmetry-breaking process of the SU(3)×SU(2)×U(1) standard model is expected to occur in the physical Universe, we are considering inflation there.…”

Bounds on the Nonminimal Coupling of the Higgs Boson to Gravity

“…This coupling is particularly important in models of "induced gravity" where the scale scale is generated spontaneously by setting M = 0 and requiring that ξ ≃ 10 32 [10,15,21]. Such a setup was also shown to be able to produce good inflation with the standard model Higgs boson acting as the inflaton [11].…”

Bounds on the Effective Theory of Gravity in Models of Particle Physics and Cosmology

“…It could play an important role in cosmological models [111], inflationary scenarios [112] and models of induced gravity [113,114]. Also, as mentioned in the introduction, this coupling should be generically present in the effective theory expansion unless it is forbidden by a symmetry.…”

“…This coupling is particularly important in models of "induced gravity" where the Planck scale is generated spontaneously by setting M = 0 and requiring that ξ 10 32 [111,114,113]. Such a setup was also shown to be able to produce good inflation with the standard model Higgs boson acting as the inflaton [112].…”
