We report on a search for B(0)(s)-->micro(+)micro(-) and B(0)(d)-->micro(+)micro(-) decays in pp collisions at square root of s=1.96 TeV using 171 pb(-1) of data collected by the CDF II experiment at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the standard model. One event survives all our selection requirements, consistent with the background expectation. We derive branching ratio limits of B(B(0)(s)-->micro(+)micro(-))<5.8x10(-7) and B(B(0)(d)-->micro(+)micro(-))<1.5x10(-7) at 90% confidence level.
我们报告了在费米实验室万亿电子伏特加速器的CDF II实验中，利用收集到的171皮靶⁻¹的数据，在质心能量√s = 1.96 TeV的质子-质子碰撞中寻找B⁰(s)→μ⁺μ⁻和B⁰(d)→μ⁺μ⁻衰变的结果。这些稀有过程的衰变率对超出标准模型的物理贡献很敏感。一个事件满足了我们所有的选择要求，与背景预期一致。我们在90%置信水平下得出B(B⁰(s)→μ⁺μ⁻)<5.8×10⁻⁷和B(B⁰(d)→μ⁺μ⁻)<1.5×10⁻⁷的分支比上限。
