Description: Dihadron correlations in nuclear collisions continue to serve as an important tool for accessing energy loss and medium modification of jet shapes and yields, particularly in comparison to p+p reference data. However, there remain unsettled issues in the methodology and interpretation of dihadron correlations. In particular, the disentanglement and subtraction of event anisotropy from a correlated and (possibly highly quenched) jet signal in a large heavy-ion background is not a closed case. A new technique for reducing background in a triggered correlation analysis is to require trigger particles to reside within the cone radius of a reconstructed jet. A simulation study of the influence of background on dihadron correlations is presented together with improvements afforded by using jet reconstruction for purity enhancement of trigger particles. Additionally, progress using these techniques in Au+Au data from the STAR detector is reported along with discussion of their relation to existing results.

Title: Understanding jet shapes with π 0–h ± correlations
Subject: Energetic Particles ; Correlation ; Nuclear Matter ; Energy Dissipation ; Pair Rate ; Partonic Energy Loss ; Phenix Experiment ; Energy Loss Model ; Monte Carlo Routine
Description: Angular correlations involving energetic particles associated with partonic jet fragmentation provide an important opportunity to study the hot nuclear matter produced in A+A collisions, particularly when compared against a p+p reference. Recent results from di-hadron correlations suggest that jet observables from A+A and p+p differ considerably at low pT but approach comparable values as pT increases above 7 GeV/c, providing clues on the nature of partonic energy loss and the medium response. The most recent π0-triggered jet correlation results from the PHENIX experiment are presented, as well as a quantitative study of the jet-peak widths and shapes.

### High- p t jet fragmentation in au+au collisions

Title: High- p t jet fragmentation in au+au collisions
Subject: Physics;
Description: The large single-particle high- p T suppression ( R AA ) observed in heavy-ion collisions at RHIC energies suggests a considerable loss of energy by hard-scattered partons. Additional experimental information is sought to improve the understanding of medium-induced energy loss beyond that given by R AA . Angular di-jet correlations are an important experimental probe currently available to investigate the mechanisms giving rise to jet quenching in heavy-ion collisions. In a comparison between Au+Au and p + p , it is observed that the quantities representing jet widths and shapes for the two species become comparable at high transverse momentum ( p T > 7GeV/ c ). This apparent similarity is interpreted as being due to some combination of the following: (a) an inability of di-jet correlations to serve as a penetrating probe of the medium, or (b) minimal medium-induced modification of the observed high- p T jets due to large fluctuations in energy loss probabilities. Additional experimental probes are discussed which offer the possibility to discriminate between such explanations.
