利用Belle与CLEO实验组的最新实验数据 ,分析了B→D( ) π衰变道的同位旋振幅与位相差 ,并确定了相关的因子化参数 .结果表明这类衰变道中的强相互作用效应不可忽略 ,但是因子化近似对于单个同位旋振幅仍旧是合理与自洽的 .
Based on the latest experimental data of Belle and CLEO experimental groups, the isospin amplitude and phase difference of the B → D () π decay channel are analyzed and the relevant factorization parameters are determined. The results show that the strong interaction in this decay channel can not Ignored, however, the factorization approximation is still reasonable and self-consistent for a single isospin amplitude.
