Recent high-pt results from STAR


الملخص بالإنكليزية

We present selected recent results of multi-hadron correlation measurements in azimuth and pseudorapidity at intermediate and high pt{} in Au+Au collisions at $sqrt{s_{NN}}=200$ GeV, from the STAR experiment at RHIC. At intermediate pt, measurements are presented that attempt to determine the origin of the associated near-side (small dphi) yield at large pseudo-rapidity difference deta{} that is found to be present in heavy ion collisions. In addition, results are reported on new multi-hadron correlation measures at high-pt{} 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.
