Energy Loss of a Heavy Quark Produced in a Finite Size Medium
We study the medium-induced energy loss −∆E0(Lp) suffered by a heavy quark produced at initial time in a quark-gluon plasma, and escaping the plasma after travelling the distance Lp. The heavy quark is treated classically, and within the same framework −∆E0(Lp) consistently includes: the loss from standard collisional processes, initial bremsstrahlung due to the sudden acceleration of the quark...
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 کاملOn the Energy Loss of High Energy Quarks in a Finite-size Quark-gluon Plasma
We study within the light-cone path integral approach the induced gluon emission from a fast quark passing through a finite-size QCD plasma. We show that the leading log approximation used in previous studies fails when the gluon formation length becomes of the order of the length of the medium traversed by the quark. Calculation of the energy loss beyond the leading log approximation gives the...
متن کاملConstraining in-medium heavy-quark energy-loss mechanisms via angular correlations between heavy and light mesons
Two-particle correlations obtained from parton showers that pass the hot and dense medium of the quark gluon plasma (QGP) can be used as an alternative observable, in addition to the combination of the nuclear modification factor RAA and the elliptic flow v2, to study the mechanisms of in-medium heavy quark energy-loss. In particular, angular correlations represent a promising tool to distingui...
متن کاملEnergy Loss of a Heavy Quark from Asymptotically AdS Geometries
We investigate some universal features of AdS/CFTmodels of heavy quark energy loss. In addition, as a specific example, we examine quark damping in the spinning D3-brane solution dual to N = 4 SU(N) super Yang-Mills at finite temperature and R-charge chemical potential.
