Direct Production of Light Scalar in the Type-I Two-Higgs-Doublet Model at the Lifetime Frontier of LHC

Wei Liu, Lei Wang, Yu Zhang

A light pseudoscalar $A$ in the sufficient large $\tan \beta$ region of type-I two-Higgs-doublet model (2HDM) can be naturally a long-lived particle (LLP). We focus on $H^{\pm }A$, $HA$…
