High energy partons are known to lose energy when passing through the hot and dense medium produced in heavy ion collisions. This energy loss is expected to depend on the mass of the fragmenting parton. For light partons, energy loss via gluon bremsstrahlung is expected to dominate, while for heavy-quarks, collisional energy loss may play a more important role. Comparisons between the...
Beauty quarks are unique probes for studying quark-gluon plasma (QGP) properties. One of the most important issues and limiting factors in understanding their energy loss and diffusion in the QGP is their hadronization. Additionally, whether they experience energy loss in the smallest systems remains an open question. We present newresults on the nuclear modification factors ($R_\mathrm{AA}$)...
We study the effect of the early stage of heavy-ion collisions on the transport of heavy quarks, by extracting two-particle correlations and nuclear modification factor [1]. We perform numerical simulations for both the temporal evolution of the initial state Glasma fields and the propagation of classical test particles in these background fields [2].
Firstly, we simulate how...
To date, holographic calculations have provided separate descriptions for the rates of energy loss either for ultrarelativistic massless quarks and gluons or for infinitely massive quarks in strongly coupled plasma, with the latter calculation valid for $\sqrt{\gamma} < M/( \sqrt{\lambda}T)$, where $\gamma$ is the Lorentz boost factor for a heavy quark with velocity $v$ and mass $M$ moving...
