Abstract

The cross section of the γγ → pp̄ reaction was measured at two-photon center-of-mass energy (Wγγ) between 2.2 and 3.3 GeV, using the two-photon process at an e+ e- collider, TRISTAN. The Wγγ dependence of the cross section integrated over a c.m. angular region of |cos θ*| <0.6 is in good agreement with the previous measurements and the theoretical prediction based on diquark model in the high Wγγ region.
