Collective Flow And Azimuthally Differential Pion Femtoscopy With The Alice Experiment At The Lhc, Vera Reneee Loggins

Wayne State University Dissertations

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 …

Centrality Dependence Of Two-Particle Number And Transverse Momentum Correlations In 200 Gev Au+Au Collisions At Rhic, Laurence Henry Tarini

Wayne State University Dissertations

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 …
