The production of two high-p_T jets in the interactions of quasi-real photons in e+e- collisions at sqrt{s_ee} from 189 GeV to 209 GeV is studied with data corresponding to an integrated e+e- luminosity of 550 pb^{-1}. The jets reconstructed by the k_T cluster algorithm are defined within the pseudo-rapidity range -1 < eta < 1 and with jet transverse momentum, p_T, above 3 GeV/c. The differential di-jet cross-section is measured as a function of the mean transverse momentum ptmean of the jets and is compared to perturbative QCD calculations.
Distribution of the total energy outside the reconstructed jets for the completed data samples. Also tabulated is the estimated background.
Distribution of the total energy outside the reconstructed jets for the 'Dir' domain. Also tabulated is the estimated background.
Distribution of the total energy outside the reconstructed jets for the 'SR' domain. Also tabulated is the estimated background.
