Radiative jet energy loss in a three-dimensional hydrodynamical medium and high $p_T$ azimuthal asymmetry of ${\pi }_0$ suppression at mid and forward rapidity at RHIC

Abstract

The nuclear modification factor $R_{AA}$ for ${\pi }_0$ production in Au+Au collisions at $\sqrt{s}=200$ AGeV 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 ${\pi }_0$ suppression at high $p_T$ in central and non-central collisions, at mid and forward rapidity. The determination of $R_{AA}$ 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 precise tomography of the nuclear medium.
