Abstract

Masses of the dimesonic (meson–antimeson) molecular states are calculated using Yukawa like and meson exchange potential in semi-relativistic approach. The digamma decay width of the dimesonic systems are evaluated using the spectroscopic parameters. Many states such as \(f_{0}(980)\), \(h_{1}(1380)\), \(a_{0}(1450)\), \(f_{0}(1500)\), \(f_{2}'(1525)\), \(f_{2}(1565)\), \(a_{2}(1700)\), \(f_{0}(1710)\), \(f_{2}(1810)\), \(f_{2}(2010)\) have shown the signature of dimesonic molecules. Their masses and digamma widths are in good agreement with other theoretical results as well as experimental measurements.
