DESCRIPTION:We use an improved K-matrix model to extract hadronic and di-p
 hoton couplings of sigma(600) and f0(980). Especially\, we are interest in
  "direct width" to gamma gamma\, which will provide important information 
 about their nature. We also find that the rescattering part of the amplitu
 de is relatively large indicating an important contribution of the meson l
 oops in the determination of the \\gamma\\gamma total width.\n\nhttps://in
