Ultra-relativistic heavy ion collisions produced at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) produce a new state of matter of deconfined quarks and gluons (partons) called the quark-gluon plasma (QGP). This plasma of deconfined but strongly coupled partons is believed to have been the primary state of matter in the universe up to a few milliseconds after the Big Bang. High energy partons produced in hard scatterings early in the collision can be used to probe the entire lifetime of the QGP. These partons propagate through and interact with the QGP before fragmenting into collimated …

Since 2009, the Large Hadron Collider (LHC) at European Organization
for Nuclear Research (CERN) has been conducting experiments in $pp$,
Pb-Pb, as well as $p$-Pb collisions with the center of mass energy
ranging $\sqrt{{s}_{NN}}=0.9-5.05$~TeV. In this thesis, both,
estimates of background correlations in anisotropic flow, $v_1-v_5$,
measurements
in Pb-Pb collisions at
$\sqrt{{s}_{NN}}=2.76$~TeV, and azimuthally differential pion femtoscopy
of Pb-Pb collisions are reported.
Two particle azimuthal correlations are statistically the most precise
method of measuring anisotropic flow. The main drawback of this method
is its sensitivity to the non-flow correlations, which unlike real
flow, do not have geometrical origin. Non-flow contribution …

We present plots of the pattern of particle formation in $sqrt{s_{NN}}=200$ GeV Au+Au heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) using three different two-particle correlation measurements of number and transverse momentum as a function of relative azimuth, pseudorapidity and centrality. All three observables show the onset of a ``ridge" feature of enhanced correlations in pseudorapidity with increasing centrality. The plots of real data are compared to plots of simulations using RQMD data and data from a simple ``cluster'' model. The intent of the analysis is to analyze the role of radial flow in the onset of the …
