Description

We calculate the cross section of J/ψ plus prompt-photon inclusive production in γγ collisions at next-to-leading order within the factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) focusing on direct photoproduction. Apart from direct J/ψ production, we also include the feed-down from directly-produced χcJ and ψ' 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. (orig.)
