Two Particle Correlations And The Ridge In Relativistic Heavy Ion Collisions
… Heavy Ion Collider (RHIC) find an enhancement of two particle correlations in relativistic heavy ion collisions, not present in proton-proton collisions. Because the correlation structure is wide in relative pseudorapidity and narrow in relative azimuthal angle, it is known as the ridge. The most …

Centrality dependence of two-particle correlations in relativistic heavy ion collisions
Results on the centrality dependence of two-particle correlations in Au+Au collisions at ... 200GeV are presented. A particular focus is devoted to investigating any anomalous behavior in the centrality dependence of correlation functions, as previous results suggest existence of such tendencies …

Two-Particle Correlations at 40, 80, and 158 AGeV Pb-Au Collisions
… this thesis, a centrality dependent study of tow-particle momentum correlations of like-sign pions (HBT interferometry) from Pb-Au collisions at beam energies of 40, 80 and 158 AGeV is presented. The three-dimensional correlation function C_2, depending on the relative momentum components of the …

Control study of two-particle correlations in heavy ion collisions at RHIC-PHENIX
… of jets in a heavy ion environment using the two- particle correlation method in the presence of a high-pT particle. These measurements have offered insight into the formation of a new state of dense nuclear matter called the Quark-Gluon Plasma (QGP) through the observation of jet quenching. …

A study of jets at the STAR experiment at the relativistic heavy ion collider via two-particle correlations
… by measuring the angular correlation between particles at high transverse momentum. Differences in the yield and shape of the angular correlations as a function of system size give information on the medium produced in the collision. Such modifications can be used to infer the presence of a …

A study of medium induced jet modificaiton at the relativistic heavy ion collider via two particle correlations and identified jet spectra
This work has studied the particle composition of jets by determining the ratios p±/π± and K±/π± in Au + Au and d + Au collisions at √sNN = 200 GeV measured by the STAR experiment at RHIC. Jets were found by measuring the angular azimuthal correlation between particles at high transverse momentum. …

Measurement of non-flow correlations and elliptic flow fluctuations in Au+Au collisions at RHIC
Measurements of collective flow and two-particle correlations have proven to be effective tools for understanding the properties of the system produced in ultrarelativistic nucleus-nucleus collisions at the Relativistic Heavy Ion Collider (RHIC). Accurate modeling of the initial conditions of a …

Properties of Fragmentation Photons in p+p Collisions at 200 GeV Center-of-Mass Energy
… momentum between 2 and 5 GeV/c. The use of two-particle correlations coupled with a sophisticated method for identifying and removing decay photons has made it possible to further study the jet properties of these fragmentation photons, in the form of pout and root mean square jT. These …

2-d Di-hadron Correlations at √sN N = 2.76 TeV using the ALICE experiment
… Ion Collider Experiment’ (ALICE). The study of two-dimensional two-particle correlations of emitted charged par- ticles carries valuable time integrated information of the dynamical QCD medium. Long-range correlations between particles in angular and momentum space generally can be attributed to …

Studies of high transverse momentum phenomena in heavy ion collisions using the PHOBOS detector
The use of high-pT particles as calibrated probes has proven to be an effective tool for understanding the properties of the system produced in relativistic heavy ion collisions. In this thesis, two such measurements are presented using the PHOBOS detector at the Relativistic Heavy Ion Collider …

Two-particle correlation studies in heavy ion collisions at the Large Hadron Collider
<p>Results on two-particle angular correlations in pPb at [square root sNN] =5.02 TeV and PbPb collisions at [square root sNN] =2.76 TeV are reported. The long-range correlations in pseudorapidity (“ridge'') has been seen in various systems, including PbPb, pPb and pp systems. In this thesis, …
