A broadened or double humped away-side structure was observed in 2-particle azimuthal jet-like correlations at RHIC and SPS. This modification can be explained by conical emission, from either Mach-cone shock waves or Čerenkov gluon radiation, and by other physics mechanisms, such as large angle gluon radiation, jets deflected by radial flow and path-length-dependent energy loss. Three-particle jet-like correlations are studied for their power to distinguish conical emission from other mechanisms. This paper discusses Mach-cone shock waves, Čerenkov gluon radiation and the experimental evidence for conical emission from RHIC and SPS.
