Abstract

Dihadron azimuthal correlations containing a high transverse momentum ($\pt$) trigger particle are sensitive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium, i.e. jet-quenching. Previous measurements revealed a strong modification to dihadron azimuthal correlations in Au+Au collisions with respect to \pp\ and \dAu\ collisions. The modification increases with the collision centrality, suggesting a path-length dependence to the jet-quenching effect. This paper reports STAR measurements of dihadron azimuthal correlations in mid-central (20-60\%) Au+Au collisions at $\snn=200$~GeV as a function of the trigger particle's azimuthal angle relative to the event plane, $\phis=|\phit-\psiEP|$. The azimuthal correlation is studied as a function of both the trigger and associated particle $\pt$. The subtractions of the combinatorial background and anisotropic flow, assuming Zero Yield At Minimum (\zyam), are described. The away-side correlation is strongly modified, and the modification varies with $\phis$, which is expected to be related to the path-length that the away-side parton traverses. The pseudo-rapidity ($\deta$) dependence of the near-side correlation, sensitive to long range $\deta$ correlations (the ridge), is also investigated. The ridge and jet-like components of the near-side correlation are studied as a function of $\phis$. The ridge appears to drop with increasing $\phis$ while the jet-like component remains approximately constant. ...
