We give an estimate for the upper bounds on rates of lepton flavor violating(LFV) decays M to mu(pm) + e(mp) of vector mesons M = rho0, omega, phi, J/psi,Upsilon and the Z0 boson in a model independent way, analyzing thecorresponding lowest dimension effective operators. These operators alsocontribute to nuclear mu-e-conversion. Based on this observation and using theexisting experimental limits on this LFV nuclear process, we show that thestudied two-body LFV decays of vector bosons are strongly suppressedindependent on the explicit realization of new physics. The upper limits on therates of some of these decays are significantly more stringent than similarlimits known in the literature. In view of these results experimentalobservation of the two-body LFV decays of vector bosons looks presentlyunrealistic.
