We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central + Au and minimum bias collisions at GeV. The charged hadron is measured at midrapidity , and the energy is measured at large rapidity (, Au-going direction). An enhanced near-side angular correlation across is observed in +Au collisions. Using the event plane method applied to the Au-going energy distribution, we extract the anisotropy strength for inclusive charged hadrons at midrapidity up to . We also present the measurement of for identified and and (anti)protons in central + Au collisions, and observe a mass-ordering pattern similar to that seen in heavy-ion collisions. These results are compared with viscous hydrodynamic calculations and measurements from + Pb at = 5.02 TeV. The magnitude of the mass ordering in +Au is found to be smaller than that in +Pb collisions, which may indicate smaller radial flow in lower energy +Au collisions.
