Endpoint of the Electroweak Phase Transition Using the Auxiliary Mass Method
K. Ogure, Joe Sato · Progress of Theoretical Physics · 2000
We study the end-point of the Electroweak phase transition using the auxiliary mass method. The end point is $m_H\sim40$ (GeV) in the case $m_t=0$ (GeV) and strongly depends on the top quark mass. A first order phase transition disappears at $m_t\sim 160$ (GeV). The renormalization effect of the top quark is significant.
