Hard $γγ$ Collisions at Future $e^+ e^-$ LINACs

Abstract

We update our previous calculation of di--jet production in two--photon collisions at future \ee\ colliders, including both beam-- and bremsstrahlung. We then discuss the production of heavy ($c,b,t$) quarks. Our study re--confirms that colliders with much beamstrahlung offer no physics advantages over designs with little beamstrahlung.
