Physics Objectives for Future Studies of the Spin Structure of the Nucleon
Wolf-Dieter Nowak
Physics perspectives are shown for future experiments in electron or positron scattering on nucleons, towards a deep and comprehensive understanding of the angular momentum structu…
The Physics Case for Polarised Proton-Nucleon Scattering at HERA
V. A. Korotkov, W. -D. Nowak
The physics case for a possible fixed target polarized nucleon-nucleon collision experiment at HERA is described. The experiment named HERA-N could be realized using an internal po…
Color Octet Contribution to J/psi Photoproduction Asymmetries
George Japaridze, Wolf-Dieter Nowak, Avto Tkabladze
We investigate photoproduction asymmetries in the framework of the NRQCD factorization approach. It is shown that the color octet contribution leads to large uncertainties in…
Theory Meets Experiment for the Determination of
D. von Harrach, W. -D. Nowak, J. Soffer
We briefly summarize the main points made during the discussion session on the determination of , where all Workshop participants were strongly encouraged to contribute.
Double Spin Asymmetries in Charmonium Hadroproduction at HERA-
W. -D. Nowak, O. Teryaev, A. Tkabladze
We discuss the double spin asymmetries in charmonium hadroproduction with nonzero transverse momenta at fixed target energies, GeV, within the framework of the f…
On a Possibility to Determine the Sign of the Polarized Gluon Distribution
W. -D. Nowak, A. V. Sidorov, M. V. Tokarev
We investigate the possibility to draw conclusions on the sign of the spin-dependent gluon distribution, , from existing polarized DIS data. The spin-dependent parton d…
