Multiple Interactions in Two-Photon Collisions

Abstract

We compute cross sections for events where two pairs of partons scatter off each other in the same $\gamma \gamma$ reaction, giving rise to at least 3 high--{\mbox{$p_T^{}$}} jets. Unlike in {\mbox{$p\bar{p}$}}\ collisions we find the signal to lie well above the background from higher order QCD processes. If the usual ``eikonaliztion" assumption is correct, the signal should be readily observable at LEP2, and might already be detectable in data taken at TRISTAN.
