Abstract
We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central and minimum bias collisions at . 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 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 (anti)protons in central 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 at . The magnitude of the mass ordering in is found to be smaller than that in collisions, which may indicate smaller radial flow in lower energy collisions.
