Beam-Energy Dependence of Directed Flow of Protons, Antiprotons and Pions in Au+Au Collisions

STAR Collaboration, L. Adamczyk, J. K. Adkins +351

Rapidity-odd directed flow($v_1$) measurements for charged pions, protons and antiprotons near mid-rapidity ($y=0$) are reported in $\sqrt{s_{NN}}=$ 7.7, 11.5, 19.6, 27, 39, 62.4…
