Inclusive Production of Charged Hadrons and Jets in Photon-Photon Collision at LEP2

The inclusive production of charged hadrons and jets in the collisions of quasi-real photons (e+e− → e+e−+X) has been measured using the OPAL [1] detector at LEP. This analysis used the data taken by the OPAL-detector 1997-2000, L=616 pb−1 (hadrons) and 1998-2000, L=593 pb−1 (jet).The differential cross-sections as a function of the transverse momentum and the pseudorapidity of the hadrons and jets are compared to theoretical calculations of up to next-to-leading order.
