Inclusive Two--Photon Reactions at TRISTAN

Abstract

After briefly reviewing past accomplishments of TRISTAN experiments in the field of inclusive two--photon reactions, I discuss open problems in the Monte Carlo simulation of such reactions. The main emphasis is on multiple scattering, i.e. events where at least two pairs of partons scatter within the same \gaga collision to form at least four (mini)jets. The cross section for such events might just be observable at TRISTAN. While theoretical arguments for the existence of such events are strong, they have not yet been directly observed experimentally, thereby potentially opening a new opportunity for TRISTAN experiments.
