Abstract
A search for lepton-flavor-violating process e+e-→eμ in the energy region s=984-1060MeV with the SND detector at the VEPP-2M e+e- collider is reported. The model independent 90% C.L. upper limits on the e+e-→eμ cross section, σeμ<8pb, as well as on the corresponding ϕ→eμ branching fraction, B(ϕ→eμ)<2×10-6 have been obtained, for the polar angles 55°<θ<125° of the final particles.
