Study of Jet related Two-Particle Azimuthal correlations result in d+Au and $^{3}$He+Au with PHENIX

ORAL

Abstract

Angular correlations between pairs of final state particles (2 particle correlation) is useful technique to study the properties of the Quark Gluon Plasma (QGP) in the heavy ion collision. This technique is also considered to be useful to study the small systems like d+Au to isolate cold-nuclear matter effects. Comparison of the correlation in small systems to those in Au+Au can help to identify effects from the final-state interactions in the QGP, created in Au+Au. The quantity, $R_I$, the double ratio of near- to away-side per-trigger yields divided by the same in the p+p reference, can cancel out the systematics to the level where very small modification could be observable. We present the PHENIX preliminary results for $R_I$ in d+Au and $^{3}$He+Au which reveals interesting jet modification which offers the opportunity to clarify the roles of Cold Nuclear Matter from potential Hot Nuclear Matter effects in small systems.
