22. Probing EWPT in 2HDM with Future Lepton Colliders

The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. In this talk, we focus one the a strong first order electroweak phase transition (SFOEWPT) in the type-I and type-II two Higgs doublet models (2HDM). Through a parameter space scan, we find that SFOEWPT suggests upper limits on the masses of the heavy Higgs 𝑚𝐴/𝐻/𝐻±,...

23. Higgs to dimuon discovery using quark/gluon tagging of ISR

In 2020, CMS collaboration reported the significance of 3.0$\sigma$ for the Higgs boson decay to dimuon process. We propose that by using quark/gluon tagging of the initial state radiation(ISR) jets, the significance can be considerably enhanced. We exploit the difference in the fraction of quark/gluon ISR jets of gluon-fusion Higgs signal and its background, Drell-Yan. By conducting...
