New mechanism for quark energy loss.

چکیده
We show that a heavy quark moving sufficiently fast through a quark-gluon plasma may lose energy by Cherenkov-radiating mesons. We demonstrate that this takes place in all strongly coupled, large-N{c} plasmas with a gravity dual. The energy loss is exactly calculable in these models despite being an O(1/N{c}) effect. We discuss implications for heavy-ion collision experiments.

Radiative 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...

In this paper, we have considered that the strange-star consists of quark matter from its center to surface. For quark matter, we have used two models, the MIT bag model and string-flip like model. In the bag model, the energy of the system has been considered the kinetic energy of the particles of system in addition to a constant B. We have considered two states for B, one of them is constant...
متن کاملThe uncertainties due to quark energy loss on determining nuclear sea quark distribution from nuclear Drell-Yan data
By means of two different parametrizations of quark energy loss and the nuclear parton distributions determined only with lepton-nuclear deep inelastic scattering experimental data, a leading order phenomenological analysis is performed on the nuclear Drell-Yan differential cross section ratios as a function of the quark momentum fraction in the beam proton and target nuclei for E772 experiment...
متن کاملQuark energy loss in an expanding quark-gluon plasma
We study the quark energy loss in an expanding quark-gluon plasma. The expanding plasma produced in high energy AA-collision is described by Bjorken’s model. The dependence of the energy loss on the infrared cutoff for the radiated gluons, on the quark mass, and on the initial conditions of QCD plasma is investigated. Study of the induced gluon radiation from a fast quark in a quark-gluon plasm...
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...
