Experimental Status of Photon Photon into Baryon Antibaryon Pairs
Abstract
Description
The exclusive production of baryon antibaryon pairs in the collisions of two quasi-real photons have been studied in different experiments at e+e- colliders. Results are presented for the processes gamma gamma to proton antiproton and gamma gamma to lambda antilambda. The cross-section measurements are compared with the recent analytic calculations based on the quark-diquark model predictions. Monte Carlo studies have been done to investigate the PEP-N expectations for the gamma gamma to proton antiproton process.
