Strong First Order Electroweak Phase Transition in the CP-Conserving 2HDM Revisited — •Philipp Basler1, Marcel Krause1, Margarete Mühlleitner1, Jonas Wittbrodt1,2, and Alexander Wlotzka1 — 1Karlsruher Institut für Technologie, ITP, Karlsruhe, Deutschland — 2DESY, Hamburg, Deutschland
The generation of the observed matter-antimatter asymmetry in the universe through baryogenesis cannot be explained in the Standard Model. We therefore investigate the possibility of a strong first order phase transition in the 2-Higgs-Doublet Model (2HDM) after imposing theoretical and experimental constraints. We study the type I and II 2HDM where either of the two CP-even Higgs bosons can be the Standard Model-like Higgs boson. Our results show that there is a strong interplay between the requirement of a strong phase transition and collider phenomenology with testable implications for searches at the LHC.
