This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A few microseconds after the Big Bang, the universe is believed to have existed in the form of a plasma composed of strongly interacting particles known as quarks and gluons. Although the quarks and gluons behave as asymptotically free particles in a Quark Gluon Plasma (QGP), free quarks and gluons have never been discovered in the laboratory. Experiments at the Relativistic Heavy Ion Collider (RHIC) aim to create conditions similar to the early universe by colliding heavy ions at the highest energies possible in the hope of observing a phase transition from a QGP into hadronic degrees of freedom. The response of the space time structure of the hot reaction zone created in a heavy ion collision to a phase transition is one of the many observables being studied at RHIC. Making use of the techniques of two particle intensity interferometry, also known as the HBT effect, the RHIC experiments are studying the space-time structure and dynamical properties of the region from which particles are emitted. A large spatial size and long duration of particle emission are the predicted signals for a phase transition from a QGP to a hadronic phase. In this thesis we present results on the first measurement of one dimensional K0[subscript s] K0[subscript s] interferometry by the STAR experiment at RHIC in central (small impact parameter) Au-Au collisions at center of mass energy of 200 GeV per nucleon pair. The lambda parameter, which is a measure of the sources chaoticity, is found to be consistent with unity confirming the fact that the source is mostly chaotic as measured by STAR using three particle correlations. Without taking into account the effect of the strong interaction, the invariant radius R inv is found to be large for the mean transverse mass M [subscript t] of the pair, which is about 980 MeV/c, compared to expectations from charged pion correlations at the same M [subscript t]. Including the effect of the strong interactions makes the radius parameter for the K0[subscript s] K0[subscript s] system fall within the charged pion M [subscript t] systematics. Our result serves as a valuable cross-check of charged pion measurements which are mainly affected by contributions from resonance decays and final state interactions. This is also an important first step towards a full three dimensional analysis of neutral kaon correlations as high statistics data from RHIC will be available in the near future.

Book excerpt: We report on measurements of dielectron (ee−) production in Au+Au collisions at a center-of-mass energy of 200 GeV per nucleon-nucleon pair using the STAR detector at RHIC. Systematic measurements of the dielectron yield as a function of transverse momentum (pT) and collision centrality show an enhancement compared to a cocktail simulation of hadronic sources in the low invariant-mass region (Mee

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the goals of the Relativistic Heavy Ion Collider (RHIC) Beam Energy Scan program is to explore whether signatures of the quark-gluon plasma can be turned off, search for a potential Quantum-Chromodynamic (QCD) critical point, as well as identify the phase transition between hadronic and partonic matter. This program ran from the years 2010 through 2014 and certain observables such as the directed flow of protons and higher moments of net-protons show features that may suggest some sort of transition to hadron-dominated matter below 20 GeV. The Solenoidal Tracker at RHIC (STAR) Fixed-Target program was created to extend center of mass energies below [square root sNN]= 7.7 GeV, down to [square root sNN]= 3.0 GeV, as these energies are not practical to do with colliding beams at RHIC. This will be crucial in the second phase of the Beam Energy Scan program, BES-II, as data from energies within this range may yield information of the phase transition. The capabilities of reconstructing interactions with a fixed-target geometry needed to be demonstrated for the future of the program in BES-II. In 2015, two test runs with a fixed-target geometry were done with the STAR detector; the first was Au + Au at [square root sNN] = 4.5 GeV and the second, a month later, was Al + Au at [square root sNN] = 4.9 GeV center-of-mass energy. This dissertation focuses on the asymmetric Al + Au collisions but will involve mentions of the Au + Au run. In this work, the spectra and rapidity density of [pi]− and p are measured at the top 0-5%, 5-10%, 10-15%, 15-20%, 20-25%, and 25-30% most central collisions. In addition, the "stopping" for protons will be discussed.

Book excerpt: Based on a preliminary sample of Au + Au collisions in the EOS time projection chamber at the Bevalac, we study sideward flow as a function of bombarding energy between 0.25A GeV and 1.2A GeV. We focus on the increase in in-plane transverse momentum per nucleon with fragment mass. We also find event shapes to be close to spherical in the most central collisions, independent of bombarding energy and fragment mass up to 4He.

This book was released on 2005 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transverse momentum (PT) distributions for pions, kaons, protons and antiprotons have been measured near mid-rapidity for Au+Au collisions at sNN = 62.4 GeV using the PHOBOS detector at the Relativistic Heavy-Ion Collider (RHIC) in Brookhaven National Laboratory. Particle identification is performed using the PHOBOS Time-of-Flight plastic scintillator walls and specific energy loss in the multi-layer silicon Spectrometer, which is also used for track reconstruction and momentum-determination. The spectra are corrected for all detector-dependent effects, including feed-down from weak decays. At PT 3 GeV/c, protons are measured to be the dominant species of charged hadrons and scale much faster with respect to collision centrality than mesons. This behaviour at 62.4 GeV is found to be remarkably similar to that observed in Au+Au collisions at 200 GeV, an interesting observation which should serve as an important constraint on the various mechanisms which have been proposed to describe particle production over this PT range. Baryon stopping, the transport of baryon number from intial beam rapidity, is explored through the net proton (p - p) yields at mid-rapidity. These results fill a large gap between the SPS and higher RHIC energies and as such form an important set of data for comparing to models of baryon transport mechanisms.
