Findings

Identified multiple states as dimesonic molecules.

Masses and widths agree with experimental data.

Supported meson exchange as a viable interaction model.

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.
