A Z' Model Which May Be Relevant to the New LEP Events

Abstract

A multi-Higgs model with an extra neutral gauge boson (ZZ') is introduced. One scalar Higgs boson (H2H_2) in this model decays dominantly into a photon pair. The ZZ' decay to μ+μ\mu^+\mu^- gets a much larger branching ratio than the ZZ decay to this channel. The ZZH2Z Z' H_2 vertex provides a final state from ZZ decay resembling the new l+lγγl^+l^-\gamma\gamma events at the LEP. Other promising phenomenology, such as ZllˉZZ \rightarrow l\bar l Z' is also discussed.
