Previous studies of the simplified escenario of a color antenna traversing a dense medium have led to the idea that a system of partons with a sufficiently small transverse size maintain coherence despite the multiple interactions with the dense medium, therefore radiating as a single source. Such a setup ignores important effects coming from the formation of the system which inevitably affect...

We present the first ever AdS/CFT calculation of $\hat{q}$ for a light quark jet as a function of position or, equivalently, time. Our result does not suffer from the gamma factor blow up of the usual time-independent AdS/CFT heavy quark setup and is qualitatively similar to, but about a factor of 2/3 larger than, the light flavor result from Liu, Rajagopal, and Wiedemann. Our findings can...
In relativistic heavy ion collisions, a hot medium with a high density of unscreened color charges is produced. Jets are produced at the early stages of this collision and are known to become attenuated as they propagate through the hot matter. One manifestation of this energy loss is a lower yield of jets emerging from the medium than expected in the absence of medium effects. ATLAS has...
The elliptic and triangular azimuthal anisotropies of charged particles produced in PbPb collisions at sqrt(s_NN) = 5.02 TeV are measured with the CMS detector at the LHC over an extended transverse momentum (p_T) range up to approximately 100 GeV/c. The data cover both the low-p_T (~ 1 GeV/c) region associated with hydrodynamic flow phenomena and the high-pT region where anisotropic azimuthal...
