These proceedings report preliminary measurements of correlations between mid-rapidity charged tracks and high-rapidity event activity (EA) at STAR for s NN = 200 G e V p+Au collisions taken in 2015. These correlations are intriguing because they inform the current debate over use of the Glauber model in “small” systems (here meaning p+A or d+A and denoted as “s+A”) and have implications for calculating nuclear modification and quenching observables in these systems. The results support concerns about centrality binning in p+Au collisions, and as such motivate using ratios of semi-inclusive, as opposed to fully inclusive, jet spectra to look for jet enhancement or suppression.
