Rapidity dependence of large-p_t hadron production at RHIC
Alberto Polleri, Feng Yuan
TL;DR
This paper investigates how parton energy loss varies with rapidity in RHIC collisions, predicting a decrease in quenching effects at higher rapidities due to lower medium density, especially around 3 GeV transverse momentum.
Contribution
It provides the first detailed prediction of rapidity-dependent parton energy loss effects in ultra-relativistic nuclear collisions at RHIC.
Findings
Quenching decreases at higher rapidities due to lower medium density.
Significant effects are predicted at moderate transverse momenta around 3 GeV.
Abstract
We study the dependence of parton energy loss (quenching) on rapidity in ultra-relativistic nuclear collisions at RHIC. This can provides invaluable information on the density of the medium, which should be more dilute going away from mid-rapidity, thereby reducing the effect of quenching. We predict a clear effect at moderate transverse momenta 3 GeV.
