Abstract

We report the results of a search for the decay B0→e +e-, μ+μ- and e ±μ based on an analysis of 78 fb -1 of data collected by the Belle detector at KEKB. No candidate events have been found. Upper limits on the branching fractions are calculated at the 90% confidence level: B(B0→e+e -)<1.9×10-7, B(B0 →μ +μ-)<1.6×10-7, and B(B 0→e±μ)<1. 7×10-7. A limit on the Pati-Salam leptoquark mass M LQ46 TeV/c2 is obtained at the 90% confidence level.
