X Wang, FP Huang, X Zhang - Physical Review D, 2020 - APS
Extra CP-violating source for electroweak baryogenesis can dynamically appear at finite
temperature in the complex two-Higgs doublet model, which might help to alleviate the …

Maxi-sizing the trilinear Higgs self-coupling: how large could it be?

L Di Luzio, R Gröber, M Spannowsky - The European Physical Journal C, 2017 - Springer
In order to answer the question on how much the trilinear Higgs self-coupling could deviate
from its Standard Model value in weakly coupled models, we study both theoretical and …

The CP-violating 2HDM in light of a strong first order electroweak phase transition and implications for Higgs pair production
