关于23S1介子九重态中的同位旋二重态

On the problem of the isodoublet of the 23S1 meson nonet

利用质量矩阵模型，得出MK＊（23S1）=1578～1583MeV．算出的结果与实验上测得K＊（1410）的质量1414±15MeV相差近160MeV．按照目前的结果，本文认为把K＊（1410）安排为23S，九重态中的同位旋二重态具有一定的不确定性，还有待理论和实验上进一步研究．

Based on the mass matrix model, the mass of the K＊ （23S1） is given to be 1 578 - 1 583 MeV Comparison with the experimental mass data 1 414 ＋ 15 MeV of K＊ （1410） , the present result is less than 160 MeV. According to the current result, the arrangement is that K＊ （1410） assigned to be the isodoublet of 23S1 meson nonet is uncertain, which remains to be further studied in theory and experiment.
