Event-plane-dependent dihadron correlations with harmonic v(n) subtraction in Au plus Au collisions at v root sNN=200 GeV Academic Article uri icon


  • STAR measurements of dihadron azimuthal correlations () are reported in midcentral (20-60%) Au+Au collisions at sNN=200 GeV as a function of the trigger particle's azimuthal angle relative to the event plane, s=|t-EP|. The elliptic (v2), triangular (v3), and quadratic (v4) flow harmonic backgrounds are subtracted using the zero yield at minimum (ZYAM) method. The results are compared to minimum-bias d+Au collisions. It is found that a finite near-side (||/2) correlation shows a modification from d+Au data, varying with s. The modification may be a consequence of path-length-dependent jet quenching and may lead to a better understanding of high-density QCD. 2014 American Physical Society.
