Radiative jet energy loss in a three-dimensional hydrodynamical medium and high pT azimuthal asymmetry of pi0 suppression at mid and forward rapidity in Au+Au collisions at sNN=200 GeV

The nuclear modification factor ${R}_{\mathit{AA}}$ for ${\ensuremath{\pi}}_{0}$ production in Au+Au collisions at $\sqrt{s}=200A$ GeV is calculated and studied at high transverse momenta ${p}_{T}$. The soft thermalized nuclear medium is described within the framework of relativistic ideal three-dimensional hydrodynamics. The energy loss of partonic jets is evaluated in the context of gluon bremsstrahlung in the thermalized partonic matter. We provide a systematic analysis of the azimuthal asymmetry of ${\ensuremath{\pi}}_{0}$ suppression at high ${p}_{T}$ in central and noncentral collisions at mid and forward rapidity. The determination of ${R}_{\mathit{AA}}$ as a function of ${p}_{T}$ at different azimuthal angles and different rapidities makes for a stringent test of our theoretical understanding of jet energy loss over a variety of in-medium path lengths, temperatures, and initial partonic jet energies. This lays the groundwork for a tomography of the nuclear medium.
