Searching for Charged Higgs Bosons in the \(B-L\) Supersymmetric Standard Model at the High Luminosity Large Hadron Collider

Abstract

Upon assuming the \(B-L\) Supersymmetric Standard Model (BLSSM) as theoretical framework accommodating a multi-Higgs sector, we assess the scope of the High Luminosity Large Hadron Collider (HL-LHC) in accessing charged Higgs bosons (\(H^\pm\)) produced in pairs from \(Z'\) decays. We show that, by pursuing both di-jet and tau-neutrino decays, several signals can be established for \(H^\pm\) masses ranging from about \(M_{W}\) to above \(m_t\) and \(Z'\) masses between 2.5 TeV and 3.5 TeV. The discovery can be attained, even in a background free environment in some cases, owing to the fact that the very massive resonating \(Z'\) ejects the charged Higgs bosons at very high transverse momentum, a kinematic region where any SM noise is hugely depleted.
