文摘

Inclusive jet production (e⁺e⁻→e⁺e⁻+jet+X) is studied in collisions of quasi-real photons radiated by the LEP beams at e⁺e⁻ centre-of-mass energies from 189 to 209 GeV. Jets are reconstructed using the k_{ties/22a5.gif"" alt=""perpendicular"" border=0>} jet algorithm. The inclusive differential cross-section is measured as a function of the jet transverse momentum, , in the range for pseudo-rapidities, η^jet, in the range −1.5<η^jet<1.5. The results are compared to predictions of perturbative QCD in next-to-leading order in the strong coupling constant.
