Abstract
The detection of a heavy neutral CP-even Higgs boson of the B - L Supersymmetric Standard Model (BLSSM), h ′ , with m h ′ ≃ 400 GeV , at the Large Hadron Collider (LHC) for a center-of-mass energy of s = 14 TeV , is investigated. The following production and decay channels are considered: g g → h ′ → ZZ → 4 ℓ and (with being the Missing Transverse Energy (MET)), where ℓ = e , μ , with integrated luminosity L int = 300 fb - 1 (Run 3). Furthermore, we also look into the di-Higgs channel g g → h ′ → hh → b b ¯ γ γ at the High-Luminosity LHC (HL-LHC) with an integrated luminosity of L int = 3000 fb - 1 . We demonstrate that promising signals with high signal-to-background statistical significance ( S / B ) can be obtained through the three aforementioned channels. [ABSTRACT FROM AUTHOR]
