This thesis presents the first J/psi production analysis of Au+Au reactions at forward rapidity at [square root]sNN = 200 GeV. In the second year of RHIC running, design energy was achieved in the collisions of both Au+Au ions and proton+proton reactions. The production of the J/psi is measured by the PHENIX experiment in Au+Au collisions as well as in proton-proton collisions. The scientific goal is to investigate the nature of hot, dense nuclear matter capitalizing on the unique properties of the J/psi as a probe of this matter. Recent experimental results by the NA50 collaboration at CERN strongly deviate from the conventional picture that successfully describes data at lower energies. The importance of such a measurement is demonstrated by the wide spectrum of theoretical explanations concerning the existing data. The merits of these models will be explored in a systematic and comprehensive study of the J/psi and open charm in collisions of a variety of species and energy. A survey of the theoretical models is presented and the relevant open charm and J/psi PHENIX measurements are compared.

Download A Measurement of the Polarization of J/Psi Mesons Produced in High-energy Proton-antiproton Collisions Book in PDF, ePub and Kindle
This dissertation presents an analysis of the polarization of ' J'/ y mesons produced in 'pp¢' collisions at a centre-of-mass energy of 1.8 TeV. The collisions were produced by the Fermilab Tevatron collider, the world's highest energy particle accelerator. The data were recorded by the Collider Detector at Fermilab during Run 1 of the Tevatron in 1992-1995. The 'J'/ y meson consists of a charm quark and its antiquark, and is the best-known type of quarkonium, the bound state of a heavy quark-antiquark pair. The measurement of the production polarization of 'J'/ y mesons and other quarkonia provides a test of quarkonium production models. The study of quarkonium production is important for understanding the strong nuclear force between quarks. The strong force is one of the four known fundamental forces, being responsible for binding quarks into hadrons and holding atomic nuclei together. The polarization of centrally produced 'J'/ y mesons has been measured over the transverse momentum range 4-20 GeV/'c', using an analysis of the angular distribution of their decays to [mu]+[mu]-. Decay length measurements made by CDF's silicon vertex detector allowed the promptly produced ' J'/ y mesons to be separated from those produced in ' B'-hadron decays. The prompt and 'B'-decay polarization parameters, Ã'P' and Ã' B', have both been measured. The measured value of Ã' P' is positive at intermediate 'PT', but is consistent with zero above 12 GeV/'c', in apparent disagreement with predictions of the NRQCD factorization formalism.
