Searching for a heavy neutral CP-even Higgs boson in the BLSSM at the LHC run 3 and HL-LHC
Searching for a heavy neutral CP-even Higgs boson in the BLSSM at the LHC run 3 and HL-LHC
The detection of a heavy neutral CP-even Higgs boson of the B−L Supersymmetric Standard Model (BLSSM), h′, with mh′≃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: gg→h′→ZZ→4ℓ and $gg\to h'\to{W^+W^-}\to2\ell+\slashed{E}_T$ (with $\slashed{E}_T$ being the Missing~Transverse~Energy~(MET)), where ℓ=e,μ, with integrated luminosity Lint=300 fb−1 (Run 3). Furthermore, we also look into the di-Higgs channel gg→h′→hh→bb¯γγ at the High-Luminosity LHC (HL-LHC) with an integrated luminosity of Lint=3000 fb−1. We demonstrate that promising signals with high statistical significance can be obtained through the three aforementioned channels.

Abstract
The detection of a heavy neutral CP-even Higgs boson of the B−L Supersymmetric Standard Model (BLSSM), h′, with mh′≃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: gg→h′→ZZ→4ℓ and $gg\to h'\to{W^+W^-}\to2\ell+\slashed{E}_T$ (with $\slashed{E}_T$ being the Missing~Transverse~Energy~(MET)), where ℓ=e,μ, with integrated luminosity Lint=300 fb−1 (Run 3). Furthermore, we also look into the di-Higgs channel gg→h′→hh→bb¯γγ at the High-Luminosity LHC (HL-LHC) with an integrated luminosity of Lint=3000 fb−1. We demonstrate that promising signals with high statistical significance can be obtained through the three aforementioned channels.
