Mach Cones in Quark Gluon Plasma

Abstract

The experimental azimuthal dihadron distributions at RHIC show a double peak structure in the away side ($\Delta \varphi =\pi \pm 1.2$ rad.) for intermediate $p_t$ particles. A variety of models have appeared trying to describe this modification. We will review most of them, with special emphasis in the Conical Flow scenario in which the observed shape is a consequence of the emission of sound by a supersonic high momentum particle propagating in the Quark Gluon Plasma.
