Abstract
Previous measurements in small systems indicate that the modifications of jets relative to p+p collisions is small. However, more differential measurements may reveal if any modifications do exist. Di-hadron correlations may serve as a proxy for jets as the observed hadron is likely to originate from the same parton as the jet. In these proceedings, we compare π0-hadron correlations measured with PHENIX in small systems to those observed in p+p collisions to probe any initial state effects. Several systematic uncertainties cancel when comparing the ratio of the away-side yield to the near-side yield in d+Au and 3He+Au systems to p+p, revealing a quantifiable modification in these systems. In addition, pout distributions for the p+A collisions are measured. An increasing trend in the width of the pout distributions in p+Al and p+Au compared to p+p is observed as a function of Ncoll, the number of binary nucleon-nucleon collisions. The potential implications of these measurements will be discussed.
