Inclusive jet production in photon–photon collisions at see from 189 to 209 GeV

Abstract 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 s ee 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, p T jet , in the range 5 p T jet 40 GeV for pseudo-rapidities, η jet , in the range − 1.5 η jet 1.5 . The results are compared to predictions of perturbative QCDin next-to-leading order in the strong coupling constant.
