Abstract
Di-jet production is studied in collisions of quasi-real photons radiated b y the LEP beams at e(-)e(-) centre-of-mass energies root s(ee) = 161 and 17 2 GeV. The jets are reconstructed using a cone jet finding algorithm. The a ngular distributions of direct and double-resolved processes are measured a nd compared to the predictions of leading order and nest-to-leading order p erturbative QCD. The jet energy profiles are also studied. The inclusive di -jet cross-section is measured as a function of E-T(jet) and \eta(jet)\ and compared to next-to-leading order perturbative QCD calculations. The inclu sive di-jet cross-section as a function of \eta(jet)\ is compared to the pr ediction of the leading order Monte Carlo generators PYTHIA and PHOJET. The Monte Carlo predictions are calculated with different parametrisations of the parton distributions of the photon. The influence of the 'underlying ev ent' has been studied to reduce the model dependence of the predicted jet c ross-sections from the Monte Carlo generators.
