摘要 利用雷吉轨迹理论和介子九重态质量混合公式两种方案,对31S0介子九重态中同位旋标量态(主要是ss—成分)的质量给出预言,两种方案分别给出1853MeV和1849±12MeV.两种方案自洽的结果,将为实验上寻找该态的候选者提供帮助. By using the two approaches, Regge trajectory and meson mixing, we estimate the mass of the isoscalar state ( composed mostly of ss^- quarks) of the 3^1S0 meson nonet. The two approaches respectively give the values of 1853 MeV and 1849 ± 12 MeV, which would be useful for searching for the candidate of this state experimenfly.
