By using the two approaches, Regge trajectory and meson mixing, we estimate the mass of the isoscalar state ( composed mostly of s s— quarks) of the 3 1S-0 meson nonet.
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。
At the same time, due to 2~1S_0、 3_1S_0 are the radical excitations of 1~1S_0,we can use Regge trajectory on t.
在这里,我们主要做了三方面的工作:1)在介子—介子混合框架下,估计了3~1S_0介子九重态中同位旋标量态(?)的质量(1900±12MeV);同时考虑到2~1S_0、3~1S_0为1~1S_0的径向激发态,在(n,M~2)雷吉轨迹图中应该具有近似相同的斜率,利用雷吉轨迹可以得到其对应质量为(1926MeV),两种方法得到了两个十分自洽的结果。
