We present the results of a search for the flavor-changing neutral current decay B(0)(s)--> mu(+) mu(-) using a data set with integrated luminosity of 240 pb(-1) of pp collisions at sqrt[s] = 1.96 TeV collected with the D0 detector in run II of the Fermilab Tevatron collider. We find the upper limit on the branching fraction to be B(B(0)(s)--> mu(+) mu(-)) < or= 5.0 x 10(-7) at the 95% C.L. assuming no contributions from the decay B(0)(d)--> mu(+) mu(-) in the signal region. This limit is the most stringent upper bound on the branching fraction B(0)(s)--> mu(+) mu(-) to date.
我们展示了利用费米实验室万亿电子伏特加速器（Tevatron）对撞机运行II期使用D0探测器收集的质心能量为√s = 1.96 TeV的质子-质子对撞数据集，积分亮度为240 pb⁻¹，来寻找味改变中性流衰变B⁰(s)→μ⁺μ⁻的结果。在95%置信水平下，假设信号区域中不存在B⁰(d)→μ⁺μ⁻衰变的贡献，我们发现分支比的上限为B(B⁰(s)→μ⁺μ⁻)≤5.0×10⁻⁷。该限制是迄今为止对分支比B⁰(s)→μ⁺μ⁻最严格的上限。
