Three-Particle Azimuthal Correlations
نویسنده
چکیده
Two-particle azimuthal correlations in central Au+Au collisional at RHIC have revealed a broadened away-side structure, with respect to perpherial Au+Au, pp, and d+Au. This could be explained by different physics mechanisms such as: large angle gluon radiation, deflected jets, Ĉerenkov gluon radiation, and conical flow generated by hydrodynamic shock-waves. We can discriminate the scenarios with conical emission, Ĉerenkov radiation and conical flow, from the other mechanisms though three-particle correlations. In addition, the associated particle pT dependence can be used to distinguish conical flow from simple Ĉerenkov gluon radiation. We will discuss three-particle correlation analyses that have been performed at RHIC and what can be done at the LHC.

Analysis Method for Jet-Like Three-Particle Azimuthal Correlations
Jet-like three-particle azimuthal correlations can discriminate various physical scenarios that have been proposed to explain the observed strong modification to twoparticle azimuthal correlations. The three-particle correlation analysis is notoriously difficult in heavy-ion collisions due to the large combinatorial backgrounds. We describe the general idea behind the jet-like three-particle az...
متن کاملSearch for Conical Emission with Three-Particle Correlations
We present preliminary STAR results on 3-particle azimuthal angle correlation studies in Au+Au collisions at √ sNN = 200 GeV. The studies are carried out at mid-rapidity between a trigger particle with 3 ≤ p⊥ ≤ 4 GeV/c and two associated particles in 1 ≤ p⊥ ≤ 2 GeV/c. A cumulant analysis reveals finite 3particle azimuthal correlations, dominated by near and away side particle correlations consi...
متن کاملIdentification of exotic jet topologies via three particle correlations in PHENIX
Modifications of jet properties resulting from the coupling of jets to the strongly interacting matter produced in RHIC collisions are of great current interest. In recent work, the PHENIX collaboration has applied a novel technique to the analysis of two particle azimuthal correlations which extinguishes the harmonic part of the underlying event revealing the true jet shape. Recent extensions ...

متن کاملMeasurement of long-range multiparticle azimuthal correlations with the subevent cumulant method in $pp$ and $p$+Pb collisions with the ATLAS detector at the CERN Large Hadron Collider
A detailed study of multiparticle azimuthal correlations is presented using pp data at √ s = 5.02 and 13 TeV, and p+Pb data at √sNN = 5.02 TeV, recorded with the ATLAS detector at the CERN Large Hadron Collider. The azimuthal correlations are probed using four-particle cumulants cn{4} and flow coefficients vn{4} = (−cn{4})1/4 for n = 2 and 3, with the goal of extracting long-range multiparticle...
