Scanning the Quark-Gluon Plasma with Charmonium
B. Z. Kopeliovich, A. Polleri, J. Huefner
We suggest the variation of charmonium suppression with Feynman x_F in heavy ion collisions as a novel and sensitive probe for the properties of the matter created in such reaction…
Nuclear Shadowing and Coherence Length for Longitudinal and Transverse Photons
B. Z. Kopeliovich, J. Raufeisen, A. V. Tarasov
Motivated by the recent results for DIS off nuclei from the HERMES experiment we have performed a systematic study of shadowing for transverse and longitudinal photons. We found th…
Charmonium Suppression in Heavy Ion Collisions by Prompt Gluons
J. Huefner, B. Z. Kopeliovich
In relativistic heavy ion collisions, also the bremsstrahlung of gluons in the fragmentation regions of the nuclei suppresses the produced charmonium states. In the energy range of…
J/ΨN and Psi' N total cross sections from photoproduction data: failure of vector dominance
Joerg Huefner, B. Z. Kopeliovich
Values for the cross sections and are of crucial importance, once one wants to understand nuclear suppression of () in a search for the qua…
Electroproduction of vector mesons off nuclei at ELFE: exact solution for color transparency
J. Hüfner, B. Z. Kopeliovich
A multichannel evolution equation is developed for the density matrix describing a hadronic wave packet produced by a virtual photon and propagation through a nuclear matter. This…
