Recent high-pT results from STAR

Abstract

We present selected recent results of multi-hadron correlation measurements in azimuth and pseudorapidity at intermediate and high p T in Au+Au collisions at , from the STAR experiment at RHIC. At intermediate p T , measurements are presented that attempt to determine the origin of the associated near-side (small Δφ) yield at large pseudo-rapidity difference Δη that is found to be present in heavy ion collisions. In addition, results are reported on new multi-hadron correlation measures at high-p T that use di-hadron triggers and multi-hadron cluster triggers with the goal to constrain the underlying jet kinematics better than in the existing measurements of inclusive spectra and di-hadron correlations.
