摘要：

We calculate the cross section of J/psi plus jet inclusive production in gamma gamma collisions at next-to-leading order within the factorization formalism of non-relativistic quantum chromodynamics (NRQCD) focusing on direct photoproduction. Apart from direct J/psi production, we also include the feed-down from directly-produced Xc(J) and psi' mesons. We discuss the analytical calculation, in particular, the treatment of the various types of singularities and the NRQCD operator renormalization, in some detail. We present theoretical predictions for the future e(+)e(-) linear collider TESLA, taking into account both brems- and beamstrahlung. (c) 2005 Elsevier B.V. All rights reserved.
