Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories
Wei Su, Anthony G. Williams, Mengchao Zhang
The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatte…
Hunting for top partner with a new signature at the LHC
Daohan Wang, Lei Wu, Mengchao Zhang
Vector-like top partner plays a central role in many new physics models which attempt to address the hierarchy problem. The top partner is conventionally assumed to decay to a quar…
Demystifying Freeze-In Dark Matter at the LHC
Kyu Jung Bae, Myeonghun Park, Mengchao Zhang
Freeze-in mechanism provides robust dark matter production in the early universe. Due to its feeble interactions, freeze-in dark matter leaves signals at colliders which are often…
