We give an estimate for the upper bounds on rates of lepton flavor violating (LFV) decays M\ensuremath→\ensuremathμ^\ifmmode±\else\textpm\fie^\ensuremath∓ of vector mesons M=\ensuremathρ0, \ensuremathω, \ensuremathφ, J/\ensuremathψ, \ensuremathΥ and the Z0 boson in a model-independent way, analyzing the corresponding lowest dimension effective operators. These operators also contribute to nuclear \ensuremathμ\ensuremath-e-conversion. Based on this observation and using the existing experimental limits on this LFV nuclear process, we show that the studied two-body LFV decays of vector bosons are strongly suppressed independent on the explicit realization of new physics. The upper limits on the rates of some of these decays are significantly more stringent than similar limits known in the literature. In view of these results, experimental observation of the two-body LFV decays of vector bosons looks presently unrealistic.
