The Bubble Wall Velocity in Local Thermal Equilibrium and Energy Budget with Full Effective Potential
Zongguo Si, Hongxin Wang, Lei Wang +2
We develop a framework based on the full one-loop finite-temperature effective potential model, within which the bubble wall velocity is calculated using the local thermal equilibr…

Exploring multi-step electroweak phase transitions in the 2HDM+
Zong-guo Si, Hong-xin Wang, Lei Wang +1
Multiple electroweak phase transitions occurring sequentially in the early universe can give rise to intriguing phenomenology, compared to the typical single-step electroweak phase…
