Mass spectra of dimesonic states in light flavour sector

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), $f{}_2^{\prime }$(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.
