K. Ogure, J. Sato
TL;DR
This paper investigates the end-point of the Electroweak phase transition using the auxiliary mass method, highlighting the dependence on the top quark mass and the significance of renormalization effects.
Contribution
It introduces the auxiliary mass method to analyze the phase transition end-point and quantifies its dependence on top quark mass and Higgs mass.
Findings
End point at m_H ~ 40 GeV for m_t=0 GeV
First order transition disappears at m_t ~ 160 GeV
Renormalization effects of the top quark are significant
Abstract
We study the end-point of the Electroweak phase transition using the auxiliary mass method. The end point is (GeV) in the case (GeV) and strongly depends on the top quark mass. A first order phase transition disappears at (GeV). The renormalization effect of the top quark is significant.
