Quarkonium production in photon-photon collisions — •Luminita Mihaila, Michael Klasen, Bernd A. Kniehl, and Matthias Steinhauser — II.Inst.f.Theor.Physik, Universität Hamburg

We have calculated the production of quarkonium states in association with two jets in photon-photon collisions within the framework of NRQCD. Color singlet and color octet S- and P-wave states are consistently included. We present numerical predictions for the transverse momentum and rapidity distribution of the quarkonium at LEP 2 and at future electron-positron and photon-photon colliders.
