Title: Jet Measurements with Neutral and Di-jet Triggers in Central Au + Au Collisions at $\sqrt{s_{N N}} = 200 GeV$ with STAR

Abstract

We present two measurements related to jet production in p+p and central Au+Au collisions at $$\sqrt{s}$$NN=200 GeV. Firstly, a study of semi-inclusive charged recoil jets coincident with high-pT direct-photon and neutral pions, and secondly, the hadron correlations with respect to reconstructed di-jet triggers. Indication of medium effects is observed by comparing γ+jet and π⁰+jet measurements. In conclusion, the di-jet+hadron study shows signs that the medium-induced modifications of an imbalanced set of di-jets with “hard cores” primarily affect the recoil jet.

Measurements of jet quenching with semi-inclusive hadron+jet distributions in $Au + Au$ collisions at $\sqrt{s_{N N}} = 200$ GeV

Journal Article Adamczyk, L. ; Adkins, J. K. ; Agakishiev, G. ; ... - Physical Review C

Here, the STAR Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum hadron trigger, in central and peripheral Au+Au collisions at √^sNN = 200 GeV. Charged jets are reconstructed with the anti-k_T algorithm for jet radii R between 0.2 and 0.5 and with low infrared cutoff of track constituents (p_T > 0.2 GeV/c). A novel mixed-event technique is used to correct the large uncorrelated background present in heavy ion collisions. Corrected recoil jet distributions are reported at midrapidity, for charged-jet transverse momentum p^ch_T,jet < 30 GeV/c. Comparison is made to similar measurements formore »« less

Jet-like correlations with direct-photon and neutral-pion triggers at $\sqrt{s_{N N}} = 200 GeV$

Journal Article Adamczyk, L. ; Adkins, J. K. ; Agakishiev, G. ; ... - Physics Letters B

Azimuthal correlations of charged hadrons with direct-photon (γ_dir) and neutral-pion (π⁰) trigger particles are analyzed in central Au+Au and minimum-bias p + p collisions at √^sNN = 200 GeV in the STAR experiment. The charged-hadron per-trigger yields at mid-rapidity from central Au+Au collisions are compared with p + p collisions to quantify the suppression in Au+Au collisions. The suppression of the away-side associated-particle yields per γ_dir trigger is independent of the transverse momentum of the trigger particle (p^trig_T), whereas the suppression is smaller at low transverse momentum of the associated charged hadrons (p^assoc_T). Within uncertainty, similar levels of suppression aremore »« less

Energy dependence of acceptance-corrected dielectron excess mass spectrum at mid-rapidity in $Au + Au$ collisions at $\sqrt{s_{NN}} = 19.6$ and 200 GeV

Journal Article Adamczyk, L. ; Adkins, J. K. ; Agakishiev, G. ; ... - Physics Letters B

The acceptance-corrected dielectron excess mass spectra, where the known hadronic sources have been subtracted from the inclusive dielectron mass spectra, are reported for the first time at mid-rapidity |yee| < 1 in minimum-bias Au+Au collisions at √^sNN = 19.6 and 200 GeV. The excess mass spectra are consistently described by a model calculation with a broadened ρ spectral function for M_ee < 1.1 GeV/c². The integrated dielectron excess yield at √^sNN = 19.6 GeV for 0.4 < M_ee < 0.75 GeV/c², normalized to the charged particle multiplicity at mid-rapidity, has a value similar to that in In + In collisionsmore »« less
