Particle-Type Dependence of Azimuthal Anisotropy and Nuclear Modification of Particle Production in [Formula presented] Collisions at [Formula presented]
We present STAR measurements of the azimuthal anisotropy parameter [Formula presented] and the binary-collision scaled centrality ratio [Formula presented] for kaons and lambdas ([Formula presented]) at midrapidity in [Formula presented] collisions at [Formula presented]. In combination, the [Formula presented] and [Formula presented] particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish [Formula presented] as the value where the centrality dependent baryon enhanc...
