Book excerpt: We have studied one and two-dimensional intermittency in S+S collisions at 200 GeV/nucleon in a high statistics electronic measurement at the CERN SPS using pad-readout streamer tubes. We observe no intermittency signal beyond that produced by folding the Fritiof event generator with a detailed model of our detector. Even though the observed signal contains significant distortions due to experimental effects, we show that we are sensitive to intermittency in the collision.

This book was released on 2006 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Further, hadron production in p+Au interactions is compared to that of n+Au interactions. The single charge difference between a p+Au and a n+Au collision allows for a unique study of the ability of the interaction to transport the proton from the initial deuteron to mid-rapidity. However, no asymmetry between the positively and negatively charged hadron spectra of p+Au and n+Au interactions is observed at (qr) = 0.8. Collision centrality was determined using several different observables, including those based on the multiplicity in different regions of pseudorapidity and those based on the amount of nuclear spectator material. It is shown that measurements made on small collision systems in the mid-rapidity region are biased by centrality variables based on the mid-rapidity multiplicity. Despite this bias, a smooth evolution with centrality is observed in the Cronin enhancement of hadrons produced in d+Au collisions. It is shown that this smooth progression is independent of the choice of centrality variable when centrality is parametrized by the multiplicity measured near mid-rapidity.

Available in PDF, EPUB and Kindle. Book excerpt: Central S+S, S+Ag and S+Au collisions at 200 GeV/nucleon were studied in experiment NA35 at the CERN SPS. Recent results on strange particle production as well as the preliminary results on antiproton production are presented and discussed. Enhanced strangeness production relative to the pion and antiproton yields is observed in nucleus-nucleus collisions relative to p-p and p-A. Microscopic string models fail to consistently describe the available set of data.

Available in PDF, EPUB and Kindle. Book excerpt: Collisions of deformed uranium (238U) nuclei are studied using Glauber Monte-Carlo simulations in an effort to elucidate the effects of the non-symmetric rotations of prolate spheroid nucleus geometry and impact parameter. The nucleon density distribution is given by a three parameter Woods-Saxon density function and a Glauber Model is used in a Monte-Carlo simulation of U+U collisions. The number of participant nucleons and number of nucleon-nucleon collisions is determined and compared to the results found for gold using the same model. Simulations of uranium collisions shows that tip to tip U+U collisions increase energy density by 35% while body to body collisions decrease energy density by 10% compared to central Au+Au collisions. It is also shown that a cut on the top 5% of the charged multiplicity density per unit transverse area results in no significant increase or decrease in collision energy density. Finally, plots of predicted Upsilon production values show expected Upsilon production of collisions at various impact parameters and full overlap orientations.

This book was released on 1994-04-26 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This international meeting on ultrahigh energy multiparticle phenomena started with a summary of neutrino physics, followed by a detailed review of LEP results. It moved on to the fast-breaking field of rapidity gaps, hard pomeron and small-x structure functions at both Hera and the FermiLab Tevatron. The major collider experiments at FermiLab, and in particular, the results of the top quark search were presented in complete detail. The fields of intermittency, multiplicities, correlation functions, heavy quarks, soft and semihard hadronic physics, and the particle physics aspects of cosmic rays were subjects of spirited debate.

Book excerpt: Central collisions between nuclei at relativistic energies form a hot and dense hadronic system over a large volume. Phenomenological models, as well as QCD calculations on the lattice, predict a phase transition in nuclear matter leading to deconfinement, a state of matter in which quarks and gluons are free to move inside the entire volume of the deconfined region. This new state was given the name of Quark Gluon Plasma (QGP). Based on the conjecture that collisions of heavy nuclei at high energies can create the necessary condition of a high energy density thermalized system, a series of experiments were built to search for possible signals of QGP creation. The NA35 collaboration uses a wide acceptance apparatus at the CERN SPS which detects the majority of charged hadrons (h{sup {+-}}), and neutral strange particles produced in reactions of p, 16O and 32S projectiles at 60 and 200 GeV/nucleon lab momentum on different targets. It consists of two major tracking devices which provide the momentum measurement of the charged particles: a 2 m long streamer chamber (SC) which is placed inside a 1.5 T vertex magnet, viewed by three cameras, and a 2.5x1.5x1.0 m3 Time Projection Chamber (TPC). A set of calorimeters was used as the basic trigger device of the experiment, to select central (small impact parameter) collisions. In the data presented here, a calorimeter placed in the beam path selects near head-on collisions, i.e. events where only a small amount of energy (mostly spectator nucleon energy) was detected in an angular acceptance of less than 0.3 degrees around the beam axis. The data sample consists of three systems: S+S, S+Ag and S+Au at 200 GeV/c with trigger cross section of 3, 3.2 and 6% of the total inelastic cross section, respectively.
