Description
The Standard Model extended with a complex or real singlet scalar can admit a strong first order electroweak phase transition as needed for electroweak baryogenesis. The real singlet component that mixes with the Standard Model Higgs boson leads to the possibility of di-Higgs and di-boson final states in pp collisions. The complex component can provide a dark matter (DM) candidate that leads to the possibility of a b¯b+MET final state, which is a brand new search channel at the LHC.
Focusing on these channels, I will discuss the prospective reach at the LHC for a heavy singlet-like scalar in regions of (c)xSM parameter space compatible with a SFOEWPT (and DM phenomenology).
