摘要 | The decays B-d(0), B-s(0)--> e(+)e(-), mu(+)mu(-), e(+/-)mu(-/+) are LEP I data sample collected by the L3 detector. No signals are observed, therefore upper limits at the 90% (95%) confidence levels are set on the following branching fractions: Br(B-d(0) --> e(+)e(-)) < 1.4(1.8) x 10(-5); Br(B-s(0) --> e(+)e(-)) < 5.4(7.0) x 10(-5); Br(B-d(0) --> mu(+)mu(-)) < 1.0(1.4) x 10(-5); Br(B-s(0) -->mu(+)mu(-)) < 3.8(5.1) x 10(-5); Br(B-d(0) --> e(+/-)mu(-/+)) < 1.6(2.0) x 10(-5); Br(B-s(0) --> e(+/-)mu(-/+)) < 4.1(5.3) x 10(-5); The results for B-s(0) --> e(+)e(-) and B-s(0) --> e(+/-)mu(-/+) are the first limits set on these decay models. |
