A Z' Model Which May Be Relevant to the New LEP Events
Dan-di Wu, Chung Kao
Abstract
A multi-Higgs model with an extra neutral gauge boson (Z') is introduced. One scalar Higgs boson (H2) in this model decays dominantly into a photon pair. The Z' decay to μ+μ- gets a much larger branching ratio than the Z decay to this channel. The Z Z' H2 vertex provides a final state from Z decay resembling the new l+l-γγ events at the LEP. Other promising phenomenology, such as Z → l l Z' is also discussed.
