Description
The possible detection of a heavy neutral Higgs boson $H$ predicted by the $U(1)_{B-L}$ model at the future multi-TeV muon collider for the center-of-mass energies of $\sqrt{s} = 3, 6, 10, 30, 50$ TeV with integrated luminosities of ${\cal L}_{\rm con}=1, 2, 3, 4, 10$ ${\rm ab^{-1}}$ and ${\cal L}_{\rm opt}=90, 250$ ${\rm ab^{-1}}$, is investigated. The following production and decay channels of the heavy Higgs boson through the Vector Boson Fusion (VBF) are considered: $\mu^+\mu^- \to \nu_\mu \bar\nu_\mu H \to \nu_\mu \bar\nu_\mu W^\pm W^\mp $ and $\mu^+\mu^- \to \mu^+ \mu^- H \to \mu^+ \mu^- W^\pm W^\mp$, with the subsequent decay of the Higgs boson $H$ to pairs of $W^\pm W^\mp$ and $ZZ$ bosons. We show that promising signals with good statistical significances can be obtained in di-vector bosons channel, with $\nu_\mu \bar\nu_\mu \nu_ll^\pm \bar\nu_ll^\mp$ final states. For completeness, we incorporate the Higgs-strahlung process $\mu^+\mu^- \to\mu^+ \mu^- H$.
