Abstract
This work will be focused on the analysis of the light-by-light scattering in the mass range $W_{\gamma\gamma} < 5$ GeV. Here contribution from fermionic boxes, resonance scattering
($\eta$, $\eta^{'}(958)$, $\eta_c(1S)$, $\eta_c(2S)$, $\chi_{c0}(1P) \to \gamma \gamma$) and pionic background will be compared. The total cross section for the signal and the background at midrapidity $|\eta| <$ 0.9, and in the forward rapidity range 2.0 $< \eta <$ 4.5 will be presented. Also, the differential cross section will be considered for the next run at the LHC.
