We study the flavor-changing-neutral-current process c-->u micro(+) micro(-) using 1.3 fb(-1) of pp[over ] collisions at square root s = 1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We see clear indications of the charged-current mediated D(s)(+) and D(+)-->phipi(+) --> micro(+)micro(-)pi(+) final states with significance greater than 4 standard deviations above background for the D(+) state. We search for the continuum neutral-current decay of D(+)-->pi(+) micro(+) micro(-) in the dimuon invariant mass spectrum away from the phi resonance. We see no evidence of signal above background and set a limit of B(D(+) --> pi(+) micro(+) micro(-))<3.9 x 10(-6) at the 90% C.L. This limit places the most stringent constraint on new phenomena in the c--> u micro(+) micro(-) transition.
我们使用费米实验室万亿电子伏特加速器上运行的D0探测器记录的质心能量为1.96 TeV的质子-质子对撞产生的1.3 fb⁻¹数据，研究味改变中性流过程c→uμ⁺μ⁻。我们清晰地看到了由带电流介导的D⁺(s)和D⁺→ππ⁺→μ⁺μ⁻π⁺末态的迹象，对于D⁺态，其显著性高于背景4个以上标准差。我们在远离φ共振的双μ子不变质量谱中寻找D⁺→π⁺μ⁺μ⁻的连续中性流衰变。我们未发现高于背景的信号证据，并在90%置信水平下设定了B(D⁺→π⁺μ⁺μ⁻)<3.9×10⁻⁶的上限。该上限对c→uμ⁺μ⁻跃迁中的新现象施加了最严格的限制。
