Measurements of the inclusive jets cross section in γγ interactions at TRISTAN (preliminary)
Description
Inclusive jet production in almost real γγ collisions has been measured at √s = 58 GeV in the TOPAZ detector at the TRISTAN e+e- collider. Clear jets with transverse momentum PTJ up to 8.0 GeV has been observed in the hadronic final states in the two-photon reactions by using a jet-clustering method based on a jet-cone defined in the pseudorapidity and azimuthal angle (η-φ) plane. We present the PTJ dependence of the inclusive jet cross section after correcting the limited acceptance and finite resolution effects of the detector. The comparison with different model predictions based on the quark-parton model and QCD shows a clear evidence of the effects of resolved photon processes. Some limits for various available parton distributions in the photon are also given. (author)
