摘要

Building upon the hybrid strong/weak coupling model for jet quenching, weincorporate and study the effects of transverse momentum broadening and mediumresponse of the plasma to jets on a variety of observables. For inclusive jetobservables, we find little sensitivity to the strength of broadening. Toconstrain those dynamics, we propose new observables constructed from ratios ofdifferential jet shapes, in which particles are binned in momentum, which aresensitive to the in-medium broadening parameter. We also investigate the effectof the back-reaction of the medium on the angular structure of jets asreconstructed with different cone radii R. Finally we provide results for theso called "missing-pt", finding a qualitative agreement between our modelcalculations and data in many respects, although a quantitative agreement isbeyond our simplified treatment of the hadrons originating from thehydrodynamic wake.
