Bottom quark production cross section at fixed - target pp experiments

The cross section for bottom quark production at fixed-target energies is calculated for a wide range of beam momenta. A detailed analysis is given for the HERA-B experiment. We consider both the order α 3 s cross section and the resummation of soft gluon corrections in all orders of QCD perturbation theory. The inclusive transverse momentum and rapidity distributions, including resummation, fo...

Hadro-production of Quarkonia in Fixed Target Experiments

In this talk I review the recent progress made in the calculations of quarkonia production in fixed target experiments. NRQCD organizes the calculations in a systematic expansion in αs and v, the relative velocity between the heavy quarks. Within this formalism there are octet contributions which are not included in the color singlet model. These contributions depend upon unknown matrix element...

Beauty and Charm Production in Fixed Target Experiments

We present calculations of NNLO threshold corrections for beauty and charm production in π−p and pp interactions at fixed-target experiments. Presented at the DIS 2004 Workshop, Strbske Pleso, Slovakia, 14-18 April, 2004.

D-wave heavy quarkonium production in fixed target experiments

We calculate the D-wave heavy quarkonium production at fixed target experiments under the NRQCD factorization formalism. We find that the color octet contributions are two orders of magnitude larger than color-singlet contributions if color-octet matrix elements are taken according to the NRQCD velocity scaling rules. The prediction for the production rate of 2 D-wave charmonium state agrees wi...
