On stability of electroweak vacuum during inflation

Sergey Sibiryakov, Andrey Shkerin

We study Coleman-De Luccia tunneling of the Standard Model Higgs field during inflation in the case when the electroweak vacuum is metastable. We verify that the tunneling rate is exponentially suppressed. The main contribution to the suppression is the sa ...

Why should we care about the top quark Yukawa coupling?

In the cosmological context, for the Standard Model to be valid up to the scale of inflation, the top quark Yukawa coupling y (t) should not exceed the critical value y (t) (crit) , coinciding with good precision (about 0.2aEuro degrees) with the requireme ...

Inflation, LHC and the Higgs boson

After the Higgs boson has been discovered, the Standard Model of particle physics became a confirmed theory, potentially valid up to the Planck scale and allowing to trace the evolution of the Universe from inflationary stage till the present days. We disc ...

After the Higgs boson has been discovered, the Standard Model of particle physics became a confirmed theory, potentially valid up to the Planck scale and allowing one to trace the evolution of the Universe from the inflationary stage till the present days. ...

Living beyond the edge: Higgs inflation and vacuum metastability

Javier Rubio

The measurements of the Higgs mass and top Yukawa coupling indicate that we live in a very special universe, at the edge of the absolute stability of the electroweak vacuum. If fully stable, the Standard Model (SM) can be extended all the way up to the inf ...

eHDECAY: An implementation of the Higgs effective Lagrangian into HDECAY

Roberto Contino

We present eHDECAY, a modified version of the program HDECAY which includes the full list of leading bosonic operators of the Higgs effective Lagrangian with a linear or non-linear realization of the electroweak symmetry and implements two benchmark compos ...

Effective Lagrangian Perspectives on Electroweak Symmetry Breaking

Andrea Thamm

We use an effective Lagrangian approach to address the question of the dynamics of electroweak symmetry breaking in the Standard Model (SM) and its relation to the hierarchy problem. Composite Higgs models provide a solution by describing the recently disc ...

Higgs boson mass and new physics

We discuss the lower Higgs boson mass bounds which come from the absolute stability of the Standard Model (SM) vacuum and from the Higgs inflation, as well as the prediction of the Higgs boson mass coming from the asymptotic safety of the SM. We account fo ...

Magnetic fields at first order phase transition: a threat to electroweak baryogenesis

Andrea De Simone

The generation of the observed baryon asymmetry may have taken place during the electroweak phase transition, thus involving physics testable at LHC, a scenario dubbed electroweak baryogenesis. In this paper we point out that the magnetic field which is pr ...

Initial state radiation in Majorana Dark Matter annihilations

Andrea De Simone

The cross section for a Majorana Dark Matter particle annihilating into light fermions is helicity suppressed. We show that, if the Dark Matter is the neutral Majorana component of a multiplet which is charged under the electroweak interactions of the Stan ...
