Higgs mass and vacuum stability in the Standard Model at NNLO
A bstractWe present the first complete next-to-next-to-leading order analysis of the Standard Model Higgs potential. We computed the two-loop QCD and Yukawa corrections to the relation between the
Energy budget of cosmological first-order phase transitions
The study of the hydrodynamics of bubble growth in first-order phase transitions is very relevant for electroweak baryogenesis, as the baryon asymmetry depends sensitively on the bubble wall
Stabilization of the electroweak vacuum by a scalar threshold effect
A bstractWe show how a heavy scalar singlet with a large vacuum expectation value can evade the potential instability of the Standard Model electroweak vacuum. The quartic interaction between the
The cosmological Higgstory of the vacuum instability
A bstractThe Standard Model Higgs potential becomes unstable at large field values. After clarifying the issue of gauge dependence of the effective potential, we study the cosmological evolution of
Cosmological implications of the Higgs mass measurement
We assume the validity of the Standard Model up to an arbitrary high-energy scale and discuss what information on the early stages of the Universe can be extracted from a measurement of the Higgs
Cosmological Higgs-Axion Interplay for a Naturally Small Electroweak Scale.
A new realization of the Higgs-axion interplay idea with the new feature that it leaves no sign of new physics at the electroweak scale, and up to a rather large scale, 10^{9}  GeV, except for two very light and weakly coupled axionlike states.
Higgs windows to new physics through d = 6 operators: constraints and one-loop anomalous dimensions
A bstractThe leading contributions from heavy new physics to Higgs processes can be captured in a model-independent way by dimension-six operators in an effective Lagrangian approach. We present a
