متن کاملPhoton-photon Total Inelastic Cross-section *
We discuss predictions for the total inelastic γγ cross-section and their model dependence on the input parameters. We compare results from a simple extension of the Regge Pomeron exchange model as well as predictions from the eikonalized mini-jet model with recent LEP data. It is by now established that all total cross-sections, including photopro-duction, rise as the c.m. energy of the collid...

متن کاملA Method for Measuring the Photon-photon Total Cross Section*
In the interaction of a high energy particle with a proton or nucleus, 9 the recoil spectrum of the target at very low momentum transfer is related simply. to the total cross section of the incident particle with the photon. Estimates of the size of the effect plus recent developments in low recoil techniques suggest that measurement of the photon-photon, as well as the 71 and K-photon cross se...
