Search for $Z^{\prime }$ pair production from scalar boson decay in minimal $U(1{)}_{L_{\mu }-L_{\tau }}$ model at the LHC

Abstract

We consider a model with gauged $L_{\mu }-L_{\tau }$ symmetry in which the symmetry is spontaneously broken by a scalar field. The decay of the scalar boson into two new gauge bosons is studied as a direct consequence of the spontaneous symmetry breaking. Then, a possibility of searches for the gauge and scalar bosons through such a decay at the LHC experiment is discussed. We consider the case that the mass range of the gauge boson is $\mathcal{O}(10)$ GeV, which is motivated by anomalies reported by LHCb. We will show that the signal significance of the searches for the gauge boson and scalar boson reach to $3$ and $5$ for the scalar mixing $0.012$ and $0.015$, respectively.
