Resolved Photon Processes

Abstract

After giving a very brief introduction to the resolved photon processes, I will summarise the latest experimental information from HERA, on resolved photon contribution to large pt jet production as well as to direct photon production. I will point out the interesting role that resolved photon processes can play in increasing our understanding of the dynamics of the Quarkonium production. I will then discuss the newer information on the parton content of virtual photons as well as the kt distribution of the partons in the photon. I will end by giving predictions of an eikonalised minijet model for siggg which crucially uses the experimental measurement of the abovementioned kt distribution and comparing them with data.
