英文摘要We report the results of a search for the decay B-0-->e(+)e(-), mu(+)mu(-) and e(+/-)mu(-/+) 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(-))<1.9x10(-7), B(B-0-->mu(+)mu(-))<1.6x10(-7), and B(B-0-->e(+/-)mu(-/+))<1.7x10(-7). A limit on the Pati-Salam leptoquark mass M-LQ>46 TeV/c(2) is obtained at the 90% confidence level.
