Description

The detection of a heavy neutral CP-even Higgs boson of the $B-L$ Supersymmetric Standard Model (BLSSM), $h^{\prime }$, with $m_{h^{\prime }}\simeq 400\text{GeV}$, at the Large Hadron Collider (LHC) for a center-of-mass energy of $\sqrt{s}=14\text{TeV}$, is investigated. The following production and decay channels are considered: $gg\to h^{\prime }\to ZZ\to 4\ell$ and $gg\to h^{\prime }\to W^{+}{W}^{-}\to 2\ell +\text{Missing Transverse Energy (MET))}$, where $\ell =e,\mu$, with integrated luminosity $L_{\text{int}}=300{\text{fb}}^{-1}$ (Run 3). Furthermore, we also look into the di-Higgs channel $gg\to h^{\prime }\to hh\to b\overline{b}\gamma \gamma$ at the High-Luminosity LHC (HL-LHC) with an integrated luminosity of $L_{\text{int}}=3000{\text{fb}}^{-1}$.
We demonstrate that promising signals with high signal-to-background statistical significance ($S/\sqrt{B}$) can be obtained through the three aforementioned channels.
