Abstract: We have searched for the lepton-flavor-violating decay B0K*0μ±e using a data sample of 711 fb1 that contains 772×106 BB¯ pairs. The data were collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. No signals were observed, and we set 90% confidence level upper limits on the branching fractions of B(B0K*0μ+e)<1.2×107, B(B0K*0μe+)<1.6×107, and, for both decays combined, B(B0K*0μ±e)<1.8×107. These are the most stringent limits on these decays to date.
