Large transverse momentum suppression of 's in Au+Au and d+Au collisions at GeV
A. Capella, E. G. Ferreiro, A. B. Kaidalov +1
We propose a model of suppression of 's based on two different effects: at low we take into account the shadowing corrections, while at large the suppression is pr…
Coherence Effects in Charmonium Production off Nuclei : Consequences for J/ψSuppression
A. Capella
The probabilistic Glauber formula for nuclear absorption used in the literature is only valid at low energies and . Due to energy conservation, is replaced…
Baryon and Antibaryon production at RHIC energies in the Dual Parton Model
A. Capella, C. A. Salgado, D. Sousa
We compute the mid-rapidity densities of pions, kaons, baryons and antibaryons in -- collisions at = 130 GeV in the Dual Parton Model supplemented with final sta…
Absence of anomalous stopping in heavy ion collisions
A. Capella
We show that the baryon stopping observed in heavy ion collisions both at CERN-SPS and at RHIC can be derived from the one observed in proton-proton collisions. No increase in the…
Charged multiplicities and suppression at SPS and RHIC energies
A. Capella, D. Sousa
Charged multiplicities in nucleus--nucleus collisions are calculated in the Dual Parton Model taking into account shadowing corrections. Its dependence on the number of collisions…
J/ suppression as a function of the energy of the zero degree calorimeter : can it discriminate between deconfining and comovers interaction models ?
A. Capella, D. Sousa
The ratio of over Drell-Yan cross-sections as a function of the energy of the zero degree calorimeter in collisions has been computed in a comovers interaction mode…
