Jet-perceived anisotropy revealed through high-p⊥ data

Abstract

We explore to what extent, and how, high-p⊥ data and predictions reflect the shape and anisotropy of the QCD medium formed in ultrarelativistic heavy-ion collisions at LHC energies. To this end, we use our recently developed DREENA-A framework, which can accommodate any temperature profile within the dynamical energy loss formalism. We show that the ratio of high-p⊥ v2 and (1−RAA) predictions reaches a well-defined saturation value, which is directly proportional to the time-averaged anisotropy of the evolving QGP, as seen by the jets.
