BSMPT - A Tool for the Electroweak Phase Transition in Extended Higgs Sectors — •Philipp Basler and Margarete Mühlleitner — Karlsruher Institut für Technologie, ITP, Karlsruhe, Deutschland

A first order electroweak phase transition (EWPT) is crucial for electroweak baryogenesis. Since all parameters determining the EWPT are at the electroweak scale, the collider phenomenology can be linked with the cosmological constraints. In this talk we present the code BSMPT. BSMPT can calculate the strength of the EWPT by considering the effective potential approach for a general extended Higgs sector. Further, it can calculate the global minimum of the potential at 1-loop order allowing to test the vacuum stability. Finally, BSMPT is able to determine the triple Higgs self-couplings at 1-loop order playing an important role in the search for new physics.
