Energy Loss in Nuclear Drell-Yan Process
By means of the nuclear parton distributions which can be used to provide a good explanation for the EMC effect in the whole x range, we investigate the energy loss effect in nuclear Drell-Yan process. When the cross section of lepton pair production is considered varying with the center-of-mass energy of the nucleon-nucleon collision, we find that the nuclear Drell-Yan(DY) ratio is suppressed ...
متن کاملEnergy Loss of Hard Partons in Nuclear Matter
We report on recent calculations of the medium-induced gluon radiation off hard partons. The employed path-integral formalism reduces in limiting cases to the main “jet quenching” results of the existing literature. Moreover, it describes destructive interference effects between medium-independent and medium-induced radiation amplitudes. These affect the angular distribution and L-dependence of...
متن کاملJet Quenching and Radiative Energy Loss in Dense Nuclear Matter
Since June 2000 measurements of Au + Au reactions at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory (BNL) at √ s = 56, 130, 200 AGeV (GeV per nucleon pair) have revealed a variety of novel multiparticle phenomena not observed previously in ee, ep, pp collisions at any energy nor in nuclear collisions at lower (SPS/CERN and AGS/BNL) energies ( √ s = 17, 5 AGeV)....
متن کاملHeavy quark energy loss in a nuclear medium.
Multiple scattering, modified fragmentation functions, and radiative energy loss of a heavy-quark propagating in a nuclear medium are investigated in perturbative QCD. Because of the quark mass dependence of the gluon formation time, the medium size dependence of heavy-quark energy loss is found to change from a linear to a quadratic form when the initial energy and momentum scale are increased...
متن کاملRadiative energy loss of high energy quarks in finite-size nuclear matter and quark-gluon plasma
The induced gluon radiation of a high energy quark in a finite-size QCD medium is studied. For a sufficiently energetic quark produced inside a medium we find the radiative energy loss ∆Eq ∝ L, where L is the distance passed by quark in the medium. It has a weak dependence on the initial quark energy Eq. The L 2 dependence turns to L as the quark energy decreases. Numerical calculations are per...
