Directed Flow of Identified Particles in Au + Au Collisions at $\sqrtsNN = 200$ GeV at RHIC

the STAR Collaboration

STAR's measurements of directed flow ($v_1$) around midrapidity for ${\pi }^{\pm }$, K${}^{\pm }$, K${}_S^0$, $p$ and $\bar{p}$ in Au + Au collisions at $\sqrtsNN = 200$ GeV are presented. A…
