We report our calculation of jet quenching and its azimuthal anisotropy in the high energy AA and high multiplicity pA and dA collisions. The purpose of this study is twofold. First, we improve our previous event-by-event studies, by properly implementing pt dependence in the modeling. We show that, within the jet "monography" scenario featuring a strong near-Tc-enhancement of jet energy loss, the computed high-pt nuclear modification factor RAA and the harmonic coefficients in its azimuthal anisotropy v2, 3, 4, agree well with the available data from both Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC). Second, in light of current discussions on possible final state collective behavior in the high-multiplicity pPb and dAu collisions, we examine the implication of final state jet attenuation in such collisions, by applying the same model used in AA collisions and quantifying the corresponding RpA and RdA and their azimuthal anisotropy. The high-pt Vn provide a set of clean indicators of final state energy loss. In particular we find in the most central pPb (5.02 TeV) and dAu (200 GeV) collisions, V2 is on the order of 0.01 and 0.1 respectively, measurable with current experimental accuracy. In addition, our high-pt RdA is around 0.6 which is compatible with preliminary dAu results from RHIC.
