Abstract
Quasi-real two photon γγ → pp̄ events are produced at the KEKB accelerator at an e+e- c.m. energy of 10.58 GeV, and are collected by the Belle detector. Preliminary results for γγ invariant mass (Wγγ) from 2 to 4 GeV/c2 are presented based 30.6 fb-1 of data. In comparison with the previous measurements, better statistics are achieved. This improvement will help to test QCD predictions.
