Since 2000, \nRHIC has collided various species of particles in order to disentangle and isolate the properties of the strongly \ninteracting QGP: p+p to set a baseline, d+Au to establish a control experiment, Au+Au to definitively create the QGP, \nand Cu+Cu to bridge the gap between d+Au and Au+Au.  Electron-positron pairs are a particularly effective probe of \nthe QGP because they carry no color charge.  Therefore, once created, these leptons do not interact strongly with the \nmedium.  As a result, they retain characteristics of the full time evolution and dynamics of the system.  There are \nmany features of interest in the dielectron invariant mass spectrum.  The low mass region (m<1 GeV/c2) consists \nprimarily of pairs from Dalitz decays of light hadrons and direct decays of vector mesons that can be modified by the \nmedium, while the intermediate (1<m<3 GeV/c2) and high (4<m<8 GeV/c2) mass regions are dominated by pairs \nfrom mesons containing charm and beauty respectively. Of the multitude of measurements that PHENIX has produced over \nthe last decade, one of the more mysterious and intriguing is a large enhancement of pairs in the low mass region in \ncentral Au+Au collisions compared to the p+p reference.  Current theories are unable to explain the origin of this \nexcess and a lingering question within the field is whether the presence of 'cold' nuclear matter in the \ninitial state of the collision, independent of the formation of a QGP, could possibly account for this increased \nyield.  To answer this question, this thesis explores the dielectron spectra in d+Au collisions at &#8730;sNN \n=200GeV.  The d+Au system contains the cold nuclear matter in question but cannot create the required energy density \nto form a QGP, making it an ideal place to explore these effects.  In addition, the 2008 d+Au dataset contains the \nnecessary luminosity to also dissect the high mass region of the spectrum, thereby illuminating the characteristics \nof heavy flavor production.  These include measuring the production cross sections for charm and beauty (\u03a3cc, \n\u03a3bb) as well as testing the validity of next-to-leading order \nperturbative Quantum Chromodynamics (NLO pQCD)."},{"label":"dcterms.available","value":"2015-04-24T14:46:53Z"},{"label":"dcterms.contributor","value":"Zahed,"},{"label":"dcterms.creator","value":"Kamin, Jason"},{"label":"dcterms.dateAccepted","value":"2015-04-24T14:46:53Z"},{"label":"dcterms.dateSubmitted","value":"2015-04-24T14:46:53Z"},{"label":"dcterms.description","value":"Department of Physics"},{"label":"dcterms.extent","value":"201 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59716"},{"label":"dcterms.issued","value":"2012-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2015-04-24T14:46:53Z (GMT).
