摘    要:We calculate the D s 1 (2536) ^+ decays into D*K channels,including the decay D s 1 (2536) + → D + π-K + through a virtual D*0 in a constituent quark model.Widths and S/D amplitudes ratio are in agreement with the recent Belle and BABAR data,being the results sensitive to 1 P 1 and 3 P 1 mixture.

关 键 词:衰变  波结构  介子  组成部分  夸克模型  钾通道  混合物  宽度
