Mean transverse momentum fluctuations in baryon-rich matter are driven by energy and baryon density variations, remain robust to baryon diffusion, and show splitting between protons and antiprotons.

abstract
The anisotropy parameter v_2, the second harmonic of the azimuthal particles distribution, has been measured with the PHENIX detector in Au+Au collisions at sqrt(s_NN) = 200 GeV for identified and inclusive charged particles at central rapidities (|eta| < 0.35) with respect to the reaction plane defined at high rapidities (|eta| = 3-4). The v_2 for all particles reaches a maximum at mid-centrality, and increases with p_T up to 2 GeV/c and then saturates or decreases slightly. Our results depart from hydrodynamically predicted behavior above 2 GeV/c. A quark coalescence model is also investigated.

CMS measures V_nΔ in pPb events at √s_NN = 8.16 TeV as a function of forward rapidity gap width, p_T, and multiplicity in γPb and IP Pb enriched samples, comparing to prior pp, pPb, and γp data plus event generators.
