英文摘要We perform the first search for lepton-number-violating b+ -> d(-)l(+)l'(+) decays, where l and l' stand for e or mu, using 772 x 10(6) b (b) over bar pairs accumulated at the y(4s) resonance with the belle detector at the kekb e(+)e(-) collider. no evidence for these decays has been found. assuming uniform three-body phase space distributions for the d(-)l(+)l'(+) decays, we set the following upper limits on the branching fractions at 90% confidence level.b(b+ -> d(-)e(+)e(+)) < 2.6 x 10(-6), b(b+ -> d(-)e(+mu+)) < 1.8 x 10(-6) and b(b+ -> d-mu(+)mu(+)) < 1.1 x 10(-6).
