Electroproduction of Charmonia off Nuclei
Yu. P. Ivanov, B. Z. Kopeliovich, A. V. Tarasov +1
In a recent publication we have calculated elastic charmonium production in ep collisions employing realistic charmonia wave functions and dipole cross sections and have found good…
Transverse Momentum Distribution of J/Psi's in Pb-Pb Collisions and Gluon Rescattering
Pengfei Zhuang, Joerg Huefner
The transverse momentum dependence of J/Psi suppression in relativistic heavy ion collisions is calculated from initial state gluon rescattering not only with nucleons but also wit…
Coherence Phenomena in Charmonium Production off Nuclei at the Energies of RHIC and LHC
B. Z. Kopeliovich, A. V. Tarasov, J. Huefner
In the energy range of RHIC and LHC the mechanisms of nuclear suppression of charmonia are expected to be strikingly different from what is known for the energy of the SPS. One can…
Transverse Momentum Dependence of Anomalous J/ψSuppression in Pb-Pb Collisions
Joerg Huefner, Pengfei Zhuang
The recently published data for for production in Pb-Pb collisions at 158 A GeV are analyzed. For low values of transverse energy , where normal suppression do…
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…
Excitation of Color Degrees of Freedom of Nuclear Matter and Suppression
Jörg Hüfner, Boris Z. Kopeliovich, Alberto Polleri
In high energy nuclear collisions, the conventional Glauber model is commonly used to evaluate the contribution to suppression originating from the inelastic interaction with…
