Jet Studies in STAR via 2+1 Correlations

Abstract

This paper reports analysis on jet-medium interactions and di-jet surface emission bias at RHIC, based on a new multi-hadron correlation technique called \texttt{2+1} where back-to-back high $p_T$ hadron triggers work as proxy of di-jets. In contrast with traditional correlations with single triggers, the associated hadron distributions and spectra at both trigger sides show no evident modification from d+Au to central Au+Au collisions. This observation stands for both cases when triggers pairs are symmetric($p_T>$5GeV/$c$ vs. $p_T>$4GeV/$c$) or asymmetric($E_T>$10GeV/$c$ vs. $p_T>$4GeV/$c$).
