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 sqrt(see) from 189 to 209 GeV. Jets are reconstructed using the k⊥ jet algorithm. The inclusive differential cross-section is measured as a function of the jet transverse momentum, pTjet, in the range 5 < pTjet < 40 GeV for pseudo-rapidities, ηjet, in the range - 1.5 < ηjet < 1.5. The results are compared to predictions of perturbative QCD in next-to-leading order in the strong coupling constant. © 2007 Elsevier B.V. All rights reserved.
