Search for lepton flavor violation process e+e -→eμ in the energy region √s=984-1060MeV and φ →eμ decay
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. © 2010 The American Physical Society.
