Description
Photon-photon collisions are investigated in the framework of the two-component dual parton model. The model contains contributions from direct, resolved soft, and resolved hard interactions. All free parameters of the model are determined in fits to hadron-hadron and photon-hadron cross section data. The model is shown to agree well with hadron production data from hadron-hadron and photon-hadron collisions. The multiparticle production in hadron-hadron, photon-hadron, and photon-photon collisions as predicted by the model is compared. Strong differences are only found as a function of the transverse momentum variable. The hadron production in photon-photon collisions at present and future electron-positron colliders is studied using photon spectra according to bremsstrahlung, beamstrahlung, and backscattered laser radiation. copyright 1996 The American Physical Society
