We calculate cross sections and asymmetries for slepton pair production through neutral and charged electroweak currents in polarized hadron collisions for general slepton masses and including mixing of the left-and right-handed interaction eigenstates relevant for third generation sleptons. Our analytical results confirm and extend a previous calculation. Numerically, we show that measurements...

Theoretical aspects of VMD and related approaches to real photon-hadron interaction are discussed. The work relies on special relativity, properties of linearly polarized photons, angular momentum conservation and relevant experiments. It is explained why VMD and similar approaches should not be regarded as part of a theory but, at most, as phenomenological models. A further experiment pertaini...

In the field theoretical Glauber-Gribov framework in the eikonal approximation, we show that, in hadron-nucleus collisions in the high-energy limit and under specific conditions, the rescattering contributions to the J/ψ production cross-section vanish, leading to an A1 dependence on the atomic number A – except for nuclear effects in the nucleus structure function, the so-called shadowing. We ...

We report on a calculation of the next-to-leading order QCD corrections to the partonic cross sections contributing to single-inclusive high-pT hadron production in collisions of transversely polarized hadrons. We give some predictions for the double spin asymmetry ATT for the proposed experiments at RHIC and at the GSI.
