Regarding the Ground Scalar Mesons

  • Based on the main assumption that the a0(980) and D*sJ(2317) belong to the 1 3P0 qq multiplet, the masses of the states belong to the 1 3P0 qq multiplet are estimated in the quasi-linear Regge trajectory ansatz. In the framework of meson-meson mixing, it is suggested that the a0(980), K*0(1052), f0(1099) and f0(530) constitute the ground scalar meson nonet, and that the f0(1099) is composed mostly of ss while the f0(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.

Abstract: Based on the main assumption that the a0(980) and D*sJ(2317) belong to the 1 3P0 qq multiplet, the masses of the states belong to the 1 3P0 qq multiplet are estimated in the quasi-linear Regge trajectory ansatz. In the framework of meson-meson mixing, it is suggested that the a0(980), K*0(1052), f0(1099) and f0(530) constitute the ground scalar meson nonet, and that the f0(1099) is composed mostly of ss while the f0(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.
