Observable Consequence of Anomalous Viscosity: the Ridge

Longitudinal Broadening of Quenched Jets in Turbulent Color Fields

This paper deals with the broadening of the near-side distribution of particles at intermediate transverse momentum, associated with a high momentum trigger hadron. This broadening has been observed by RHIC experiements and is commonly referred to as the ridge. Key finding of this paper is that the broadening can be attributed to the presence of turbulent color fields. The ridge would therefore be an observable consequence of the physics which also leads to the generation of an anomalous viscosity.
