Masses of di-mesonic molecular states

Abstract

Abstract. We discuss the theoretical predictions of some di-mesonic (meson-anti meson) states and compare with some prominent experimental candidates. The masses of several di-mesonic states are computed in semi relativistic approach. The two photon decay width is calculated using the wave function at the origin. The states such as f 0 (980), a 0 (980),

“…Thus we have identified f 0 (980) as the dimesonic molecular state KK  . Rathaud and Rai [33] have reported the mass of this dimesonic system as 0.9768 GeV. Our result (0.993 GeV) is in agreement with experiment (0.990 GeV) and the Rathaud and Rai result [33].…”

“…is 1.65% and 0.3% in comparison with experiment. They predicted 0 ++ and -18.38 MeV for the state and B. E. respectively of KK [33]. We have obtained -1.443 MeV for the B. E., which is close to their result.…”

“…Our two-gamma decay width is 0.0976 keV while the result of Ref. [33] is (0.0091 keV). The reason for the differences may be the different choices of potential models, different approaches to solving the Schrodinger equations, and so on.…”
