Description
The prospects of the Muon Collider promise an unprecedented potential for exploring the particle-physics energy frontier. Furthermore, the physics program from this future collider could provide both high-precision Higgs and Standard Model (SM) measurements and direct production of new particles predicted by various extensions of the SM. With these motivations, we consider the $\mu^+\mu^- \to (Z, Z') \to ZH \to l^\pm l^\mp W^\pm W^\mp$ signal with the subsequent decay of
$Z$ to pairs of $l^\pm l^\mp$ with $l=e, \mu$ and $H$ to pairs of $W^\pm W^\mp$. The projections of new physics at the future muon collider with the benchmark center-of-mass energies of $\sqrt {s}=3, 4, 5, 6, 7$ TeV and conservative integrated luminosities of ${\cal L}_{\rm con}=1, 2, 3, 4, 10$ ${\rm ab^{-1}}$, is of the order of 684 expected events for $M_{Z'}=7$ TeV, $g'_1=0.93$, and ${\cal L}=10 \hspace{0.8mm}\rm ab^{-1}$. This scenario shows that the possibility of performing measurements for the $Z'$ boson and the heavy Higgs boson $H$ is important at the future muon collider. In another scenario, we incorporate $\mu^+\mu^- \to (Z, Z') \to ZH \to l^\pm l^\mp W^\pm W^\mp$ annihilation and Vector Boson Scattering (VBS) rates of $\mu^+\mu^- \to WWZ$ into our study, as well as the Leptonic, Semi-leptonic, and Hadronic channels of the $W^\pm$ for the signal, significant impact the sensitivity of the process.
