Abstract

We report the results of a search for the decay B 0 →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(B 0 →e + e - )<1.9×10 -7 , B(B 0 →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 LQ 46 TeV/c 2 is obtained at the 90% confidence level.
