Measurement of gamma gamma ---> p anti-p production at Belle

The Belle collaboration
Phys.Lett. B621 (2005) 41-55, 2005

Abstract (data abstract)
KEK-KEKB Collider. Measurement of the cross sections for the process GAMMA GAMMA --& gt; PBAR P in the two photon centre of mass range 2.025 to 4.0 GeV and theangular regions ABS(COS(THETA)) & lt; 0.6. The data come from E+ E- collisions at a centre of mass energy of 10.58 GeV with an integrated luminosity of 89 fb-1.. Numerical values of figure 4 supplied by C.C.Kuo.
