FI: ELECTROWEAK PHASE TRANSITION AND BARYOGENESIS IN COMPOSITE HIGGS MODELS (BENEDICT VON HARLING) 
 ELENCO COMPLETO 

DATA: 21-05-2019

SEZIONE DI FIRENZE
In this talk, I present a study of the electroweak phase transition in composite Higgs models, where the Higgs arises from a new, strongly-coupled sector which confines near the TeV scale. The confinement phase transition is described in terms of the dilaton, the pseudo-Nambu-Goldstone boson of broken conformal invariance of the composite Higgs sector. From the analysis of the joint Higgs-dilaton potential it is found that the electroweak phase transition in this scenario can naturally be first-order, allowing for electroweak baryogenesis. I then discuss how a sufficient amount of CP violation €“ another key ingredient of baryogenesis €“ can be generated from quark Yukawa couplings which vary during the phase transition. Together this allows for successful electroweak baryogenesis. This scenario can be tested in complementary ways: in EDM experiments, by searching for dilaton production and deviations in Higgs couplings at colliders, and through gravitational waves at LISA.
