基于a0(980)和D^*sj(2317)属于1^3Po介子多重态这个主要假定,在准线性Regge轨迹方案下估计了1^3Po介子多重态成员的质量.在介子-介子混合的框架下,建议a0(980),K0^*(1052),f0(1099)和f0(530)组成基态标量介子九重态,并且f0(1099)主要由ss组成,而f0(530)主要是uu+dd.这些态可能分别对应已观察到的标量态a0(980),κ(900),f0(980)和f0(600)/σ.另外,在胶球为主的图像下,估计基态标量胶球的质量大约为1340MeV.给出的结果与其他不同方法给出的结果是一致的.
Based on the main assumption that the ao(980) and D^*sj(2317) belong to the 1 3P0 qq multiplet, the masses of the states belong to the 1 ^3Po qq multiplet are estimated in the quasi-linear Regge trajectory ansatz. In the framework of mesommeson mixing, it is suggested that the ao(980), K0^+(1052), f0(1099) and fo(530) constitute the ground scalar meson nonet, and that the fo(1099) is composed mostly of ss while the fo(530) is mainly uu+dd. It is supposed that these states would likely correspond to the observed scalar states a0(980), κ(900), f0(980) and f0(600)/σ, respectively. Also, in the glueball-dominace picture, the mass of the ground scalar glueball is estimated to be about 1340MeV. The agreement between the present findings and those given by other different approaches is satisfactory.
