给出了粲介子的四叉和五叉半μ衰变的 90% 置信度上限。通过对四爪顶点的研究，我们发现 B(D0→ K−π+π−μ+ν)/B(D0→ K−μ+ν) < 0.037 和 B (D0→ ( K*(892)π)−μ+ν)/B(D0→ K−μ+ν) < 0.043 。五爪顶点产生结果 B(DS+→ η′μ+ν) / B(DS+→ φμ+ν) < 1.6。
Upper limits at the 90% confidence level are presented for four- and five-prong semimuonic decays of charm mesons. From a study of four-prong vertices we find B(D0→ K−π+π−μ+ν)/B(D0→ K−μ+ν) < 0.037 and B (D0→ ( K∗(892)π)−μ+ν)/B(D0→ K−μ+ν) < 0.043 . The five-prong vertices yield the result B(DS+→ η′μ+ν) / B(DS+→ φμ+ν) < 1.6.
