An SU(2)<SUB>L</SUB>⊗U(1)<SUB>γ</SUB> model containing exotic charged leptons can allow sizeable leptonic flavor violations (LFV) and hence rare Z decays into leptons of different flavors. The rates as well as CP-violating asymmetries are constrained using available limits on LFV and data from the CERN e<SUP>+</SUP>e<SUP>−</SUP> collider LEP on Z→l<SUB>i</SUB>l<SUB>i</SUB>,l<SUB>i</SUB>=e,μ,τ. Sizeable CP-violating rate asymmetries are theoretically possible in the model and are allowed by the former data. In contrast, the measured leptonic Z widths severely constrain these asymmetries. As a result, an experimental observation of the CP asymmetries in the model seems unlikely with le...
