Conical Correlations, Bragg Peaks, and Transverse Flow Deflections in Jet Tomography — •Barbara Betz^1,2, Miklos Gyulassy³, Jorge Noronha³, Dirk Rischke^1,4, and Giorgio Torrieri^1,4 — ¹Institut für Theoretische Physik, Goethe-Universität Frankfurt — ²Helmholtz Research School, Universität Frankfurt, GSI and FIAS — ³Department of Physics, Columbia University — ⁴Frankfurt Institute for Advance Studies, FIAS, Frankfurt

New results are presented on away side jet correlations [1] computed in a variety of (3+1)d hydrodynamic scenarios extending our work in Ref. [2] to include stopped jets, the effects of possible Bragg peak deposition and transverse background expansion. We contrast pQCD and AdS string drag plasma-jet coupling dynamics [3] and discuss strategies for experimental falsification of models using tagged heavy quark jet tomography.
