Abstract

Electroweak phase transition in the simplest extension of the standard model namely two Higgs doublet model and entropy production within this framework is studied. We have considered several benchmark points which were called using BSMPT, a C++ package, within the limit of $vev/T_C>0.2$ are studied, and corresponding entropy productions are shown in this paper.
