Energy Dependence of the Cronin Effect from Non-Linear QCD Evolution
Javier L. Albacete, Nestor Armesto, Alex Kovner +2
The non-linear evolution of dense partonic systems has been suggested as one of the novel physics mechanisms relevant to the dynamics of hadron-nucleus and nucleus-nucleus collisio…
Saturation and parton level Cronin effect: enhancement vs suppression of gluon production in p-A and A-A collisions
Rudolf Baier, Alexander Kovner, Urs Achim Wiedemann
We note that the phenomenon of perturbative saturation leads to transverse momentum broadening in the spectrum of partons produced in hadronic collisions. This broadening has a sim…
Gluon Radiation and Parton Energy Loss
Alexander Kovner, Urs Achim Wiedemann
The propagation of hard partons through spatially extended matter leads to medium-modifications of their fragmentation pattern. Here, we review the current status of calculations o…
