The production of two high-pT jets in the interactions of quasi-real photons in e+ e− collisions at sqrt(s) 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 kT cluster algorithm are defined within the pseudo-rapidity range −1<eta<1 and with jet transverse momentum, pT, above 3 GeV/c. The differential di-jet cross-section is measured as a function of the mean transverse momentum <p_T> of the jets and is compared to perturbative QCD calculations.

Abstract
The production of two high-pT jets in the interactions of quasi-real photons in e+ e− collisions at sqrt(s) 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 kT cluster algorithm are defined within the pseudo-rapidity range −1File in questo prodotto:
