| Abstract | ||
| Regge model has been used to calculate photon – photon total cross section. The couplings of the exchanged soft pomeron, hard pomeron and Reggeons with photons have been calculated. It has been assumed that soft and hard pomerons couple to photons in away similar to that of the pseudo scalar mesons. A comparison with data on photon-photon total cross section shows a good agreement | ||
