Flow Effects on Jet quenching with Detailed Balance
Abstract
A new model potential in the presence of collective flow describing the interaction of the hard jet with scattering centers is derived based on the static color-screened Yukawa potential. The flow effect on jet quenching with detailed balance is investigated in pQCD. It turns out that the collective flow changes the emission current and the LPM destructive interference comparing to that in the static medium. Considering the collective flow with velocity vz along the jet direction, the energy loss is (1 - vz) times that in the static medium to the first order of opacity. The flow dependence of the energy loss will affect the suppression of high pT hadron spectrum and anisotropy parameter v2 in high-energy heavy-ion collisions.
