We present comparisons of the latest pQCD- and AdS/CFT-based energy loss models with the newest high-pT measurements from RHIC and LHC. Zero parameter predictions of energy loss from WHDG rigorously constrained to PHENIX pi0 RAA data show quantitative agreement with the measured azimuthal anisotropy and D meson suppression at LHC. pQCD predictions follow the qualitative trend of the LHC...

The jet quenching parameter \hat{q} describes the transverse momentum broadening of a high-energy parton moving through a thermal medium. In the past, several authors were able to relate this quantity to the expectation value of two light-cone Wilson lines. Recently, the results were reobtained in a systematic way by employing effective field theory methods (Soft-Collinear Effective Theory)....

A holographic calculation of the quenching of a beam of gluons with typical momenta q shining through strongly coupled quark-gluon plasma shows that such a beam is attenuated rapidly over a distance of order q^{1/3} (pi T)^{-4/3} as it propagates at the speed of light, shedding trailing sound waves with momenta of order (pi T). At larger and larger q, the trailing sound wave becomes less and...

A firm knowledge of medium-induced energy loss mechanisms in the deconfined plasma state of QCD matter is essential for our understanding of phenomena such as strong jet quenching and high-pT hadron suppression observed in high energy nuclear collisions at RHIC and LHC. Based on perturbative QCD calculations, it is commonly accepted that the radiative energy loss contribution is dominant, ...

In this talk, we explore phenomenological signatures of light quark jet quenching, modeled as falling strings within the AdS/CFT correspondence. In particular, we show that even in the simplest models, it is possible to obtain the correct qualitative behavior of the pion RAA at LHC, and we also present the quantitative predictions. We address the effect of the QCD conformal anomaly on this...

Jets physics in heavy ion reactions is an important new area of active research at the Relativistic Heavy Ion Collider (RHIC) and at the Large Hadron Collider (LHC) that paves the way for novel tests of QCD multi-parton dynamics in dense nuclear matter. At present, perturbative QCD calculations of hard probes in elementary nucleon-nucleon reactions can be consistently combined with the effects...
