Reaction Plane Dependent Away-side Modification and Near-side Ridge in Au+Au Collisions
Abstract
Description
STAR preliminary results of di-hadron correlations versus $ϕ_{s}$, the trigger particle azimuthal angle relative to the constructed event plane are reported for mid-central Au+Au collisions and compared to central Au+Au as well as minimum bias d+Au collisions. The correlations are observed to vary with $ϕ_{s}$ on both the near and away side of the trigger particle. The away-side correlation evolves from single- to double-peak with increasing $ϕ_{s}$. The near-side correlation is separated into 'jet' and 'ridge': the ridge is found to decrease with $ϕ_{s}$ while the jet remains relatively constant.
