Nature of problem:
In high energy two-photon processes in e+e- reactions, the hadronic components of the photon contribute significantly to the process. In particular, jet production in (almost real) photon-photon collisions offers an opportunity to test perturbative QCD. In addition, the understanding of the process is indispensable for designing future high energy e+e- linear colliders.
The cross sections of the resolved photon processes are calculated at the parton level by a convolution of the photon luminosity function, the photon structure functions and the sub-process cross sections. Based on the calculation, high-pt partons and remnant partons accompanied by the resolved photon processes are generated. They are subsequently hadronized, while neglecting scattered e+-.
The running times depend upon the physical parameters. In the case of a default parameter set, it takes 487 sec to calculate the cross section on a FACOM-M1800 computer, while it takes 2.85 sec to generate 1k events.
