Vectorlike quarks(VLQs)with masses at the TeV-scale have been predicted in many new physics scenarios beyond the Standard Model(SM).Based on a simplified(X,T)doublet model including the exotic vectorlike X quark(VLQ-X...

The same-sign tetralepton signature via the mixing of neutral Higgs bosons and their cascade decays to charged Higgs bosons is a unique signal in the type-Ⅱ seesaw model with the mass spectrum M_(A^(0))≈M_(H^(0))>M_...

In this study,we perform a detailed analysis on the same-sign dilepton signature in the inert doublet model.Focusing on the low dark matter mass region,we randomly scan the corresponding parameter space.Viable samples...
