Next-to-leading order QCD corrections to spin-dependent hadron-pair photoproduction
Christof Hendlmeier, Andreas Schafer, Marco Stratmann
We compute the next-to-leading order QCD corrections to the ``direct'' part of the spin-dependent cross section for hadron-pair photoproduction. The calculation is performed using…
Exclusive annihilation p pbar -> gamma gamma in a generalized parton picture
A. Freund, A. V. Radyushkin, A. Schaefer +1
Exclusive proton-antiproton annihilation into two photons at large s (~10 GeV^2) and |t|,|u| ~ s can be described by a generalized parton picture analogous to the 'soft mechanism'…
Color Transparency versus Quantum Coherence in Electroproduction of Vector Mesons off Nuclei
B. Z. Kopeliovich, J. Nemchik, A. Schaefer +1
So far no theoretical tool for the comprehensive description of exclusive electroproduction of vector mesons off nuclei at medium energies has been developed. We suggest a light-co…
from jet and prompt photon production at RHIC
O. Martin, A. Schafer
We compare theoretical results for jet and prompt photon production in polarized pp-collisions at RHIC obained with three different methods: a) the unpolarized event generator PYTH…
Towards a solution of the charmonium production controversy: k_t-factorization versus color octet mechanism
Ph. Hagler, R. Kirschner, A. Schafer +2
The cross section of χ_{cJ} hadroproduction is calculated in the k_t-factorization approach. We find a significant contribution of the χ_{c1} state due to non-applicability of the…
Radiative corrections to deeply virtual Compton scattering
A. V. Belitsky, D. Müller, L. Niedermeier +1
We discuss possibilities of measurement of deeply virtual Compton scattering amplitudes via different asymmetries in order to access the underlying skewed parton distributions. Per…
