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 …
