Abstract
Jet and di-jet production are studied in collisions of quasi-real photons collected during the LEP2 program at e+e– center-of-mass energies from 189 to 209 GeV. OPAL reports good agreement of NLO perturbative QCD with the measured differential di-jet cross sections, which reach a mean transverse energy of the di-jet system of 25 GeV. L3, on the other hand, finds drastic disagreement of the same calculation with single jet production for transverse jet momenta larger than about 25 GeV.
PACS: 13.60.Hb Total and inclusive cross sections (including deep-inelastic processes) – 14.70.Bh Photons – 13.66.Bc Hadron production in e+e– interactions
