A Four Component Picture for Jet Induced Correlations in Heavy Ion Collisions?

Abstract

These proceedings review recent results from two and three particle correlations in heavy ion collisions. In particular we discuss the modified structure of the away side jet correlations. Under the assumption that the away side can be decomposed into a punch through component at $\Delta \varphi =\pi$ and a shoulder component with a peak displaced from $\pi$ many similar properties are observed between the ridge and shoulder. The particle ratios, yields and $p_T$ spectra are in near agreement. We also highlight important future measurements, including investigating if the decomposition of the away side jet correlations remains reasonable with high $p_T$ triggers and technical improvements to the extraction of jet induced correlations.
