Description
The PHENIX Collaboration has argued that azimuthal angle dependent pi0
suppression in Au+Au at RHIC poses a challenge for perturbative QCD
energy loss models. However, recent work by Betz and Gyulassy claims
simultaneous reproduction of this set of observables with simple
pQCD-motivated energy loss formulas. We study and contrast different
bulk medium evolution models (based on hydrodynamics and covariant
transport) combined with different implementations of
Djordjevic-Gyulassy-Levai-Vitev radiative energy loss to investigate
whether, and if yes then how the nuclear-suppression vs elliptic flow
puzzle could be resolved in the DGLV framework for light partons and
heavy quarks. This is especially interesting in view of our earlier
results that showed that realistic transverse expansion of the bulk
medium reduces high-pT elliptic flow from GLV energy loss by nearly half
compared to transversely frozen evolution scenarios.
