Probing the Electroweak Phase Transition in the Flipped Two-Higgs-Doublet Model at the LHC

Jidong Du, Yun Jiang, Wei Su

We study the CP-conserving flipped (Type-Y) Two-Higgs-Doublet Model (2HDM) in the large-$\tan {\hat{I}}^2$ regime ($\tan {\hat{I}}^2>30$), focusing on its implications for electroweak phase transition…
