Lepton Flavor Violating Decays And Production Of Vector Mesonsinduced By New Gauge Boson Z'

The standard model?SM?of particle physics can explain many experimental observations of strong,weak and electromagnetic interactions is a successful theory,it cannot be an ultimate theory.So many new physics models beyond the SM have been proposed.Many new physics models have predicted the new neutral gauge boson Z?.Some of the Z?boson can have a flavor-changing?FC?coupling with SM fermion,leading to many interesting phenomenological implications.As an important tool to search for new physics beyond the SM,the lepton flavor violating?LFV?process has been extensive research in theory.Also in experiment,there is an extensive hunt for the LFV?,?,Higgs...decays.As we known,some new physical models can provide the new LFV sources.It has been shown that the branching ratio of the vector meson LFV decay and production V??_i?_j,???V can be significantly enhanced.Considering the constraints on LFV couplings of the new gauge boson Z?to SM leptons from the current experimental upper limit for the LFV process??3?',we calculate the contri-butions of Z?to the LFV decays V??_i?_jwith V?{?,J/?,??2S?,?^?n?}and????e??in E₆model,LR model,331 model and G?221?model.We find that all Z?models considered in this paper can produce significant contributions to these decay processes and make the value of branching ratio Br???e??above its experimental upper limit.The experimental upper limit of??e?can give more severe constraints on these Z?models than those given by??3e.
