Flow effects on jet profiles and multiplicities
N. Armesto
Abstract
We study the effects of low-pT collective flow on radiative energy loss from high-pT partons traversing the QCD medium created in high-energy nucleus-nucleus collisions. We illustrate this idea through three examples. Due to longitudinal flow, jet profiles at the LHC present marked asymmetries in the η× ϕ-plane, and widths in η and ϕ of particle distributions associated with a high-pT trigger at RHIC become different. Finally, transverse flow implies an increase of high-pT v2 at RHIC.
