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…
