We have searched for the lepton-flavor-violating decay B⁰ → K^*0μ ^±e∓ using a data sample of 711 fb⁻¹ that contains 772 × 10⁶ B B̅ pairs. The data were collected near the ϒð4SÞresonance with the Belle detector at the KEKB asymmetric-energy eþe− collider. No signals were observed, and we set 90% confidence level upper limits on the branching fractions of B(B⁰ →K^*0μ⁺e⁻)<1.2×10⁻⁷, B(B⁰ → K^*0μ⁻e⁺) < 1.6 × 10⁻⁷, and, for both decays combined, B(B⁰ → K …
