This book was released on 1995 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has extended this work to the highest energy beams. Multiplicity distributions of shower particles were produced in high energy collisions of 28Si at 14.5A GeV, 32S at 200A GeV, 16O at 200A GeV and 60A GeV. They have studied these distributions in small pseudorapidity intervals of the forward and backward hemispheres in their perspective of Negative Binomial Distribution. Different multiplicity parameters have been computed for the two hemispheres separately and their variations with the phase space interval size have been studied.

This book was released on 2012 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matter at very high densities and low temperatures is predicted to be in a "color superconducting" phase. At high enough densities, quark matter is in the Color-Flavor-Locked (CFL) phase, but the possible phases of matter at intermediate densities are unknown. Since the density at the core of a neutron star can be as high as a few times the nuclear saturation density, it is the most likely place to find these exotic forms of matter in the real world. The main goal of this thesis is to probe the phases of cold dense matter using neutron star physics. Studying the transport properties of different phases of dense matter that may occur in a compact star is particularly important because transport properties such as viscosity, in addition to depending on the equation of state of matter, also depend on the low-energy degrees of freedom and therefore can discriminate between different phases of dense matter more efficiently. In the first part of this thesis we calculate the mean free path and kaonic contribution to the shear viscosity of kaon-condensed color-flavor-locked (CFL-K0) phase of quark matter. In the second part we calculate the large-amplitude enhancement of the bulk viscosity of dense matter. We obtain general analytic solutions as well as numerical solutions for the amplitude-dependent bulk viscosity of dense matter which are valid for any equations of state where equilibration occurs via fermions. In the third and fourth parts, we use our general results for the bulk viscosity to calculate the damping timescales of r-mode oscillations of neutron stars due to small-amplitude and large-amplitude bulk viscosity, the instability window of the r-modes and the saturation amplitude due to "supra-thermal" enhancement of the bulk viscosity for different cases of strange quark stars, hadronic stars and hybrid stars.

This book was released on 1994 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses progress that has been made on the following seven problems: (1) (e, e(prime)p) at high momentum transfer; (2) post, acceleration effects in two-nucleon interferometry of heavy-ion collisions; (3) pion-nucleus interactions above 0.5 GeV; (4) chiral symmetry breaking in nuclei and picnic atom anomaly; (5) atomic screening on nuclear astronomical reactions; (6) QCD related work (coherent pion production from skyrmion-antiskyrmion annihilation, QCD in 1 + 1 dimensions, and correlation functions in the QCD vacuum), and (7) kaonic hydrogen atom experiment. The problems deal with various topics mostly in intermediate-energy nuclear physics. We place priority on (1) and (2), and describe them somewhat in detail below. Other problems are our on-going projects, but we are placing lower priority on them in the second and third year.

Available in PDF, EPUB and Kindle. Book excerpt: Progress on Task A centered around data analysis. E835 is now approved. It will extend E760 studies, exploring new charmonium states and featuring an upgraded detector system plus operation at 4--6 times higher luminosity. Results are given on E760 analysis. Task B has 10 papers that have either appeared in print, or have been prepared for publication. They break down into four categories; experimental physics, theoretical physics, and computer computational techniques. They are described here along with an exciting new experimental proposal to use Da[Phi]ne, the [Phi] factory that is being constructed at Frascati National Laboratory. Progress for Task C which includes participating in the D0 project at TeV I, and the photoproduction experiment, E687, at TeV II is given. While Northwestern is not participating in the top quark physics group at D0, they have been involved in the data analysis and the discussions that led to the limits on the top quark mass. Task D comprises the shared services for the Northwestern DOE contract. This includes the maintenance and operation of all computers within the HEP group. The projects supported by Task D during the past year are given. Task E progress was to resolve the apparent conflict between EMC, SMC, and SLAC results on nucleon structure functions and Bjorken sum rules. Task F covered research in hadronic decay of the tau, thermal field theory, plasma effects in astrophysics, and heavy quarkonium. Task G covers E665, a general purpose muon scattering experiment which can detect both the scattered muon and most charged and neutral hadrons produced in the forward region. The Northwest group has collaborated very closely in the past year with the Harvard group on analyses of structure functions and vector meson production in the 1991 data sample.

Book excerpt: The high energy physics research program at the University of Hawaii is directed toward the study of the properties of the elementary particles and the application of the results of these studies to the understanding of the physical world. Experiments using high energy accelerators are aimed at searching for new particles, testing current theories, and measuring properties of the known particles. Experiments using cosmic rays address particle physics and astrophysical issues. Theoretical physics research evaluates experimental results in the context of existing theories and projects the experimental consequences of proposed new theories.

Available in PDF, EPUB and Kindle. Book excerpt: Nuclear physics is presently experiencing a thrust towards fundamental phy sics questions. Low-energy experiments help in testing beyond today's stan dard models of particle physics. The search for finite neutrino masses and neutrino oscillations, for proton decay, rare and forbidden muon and pion de cays, for an electric dipole moment of the neutron denote some of the efforts to test today's theories of grand unification (GUTs, SUSYs, Superstrings, ... ) complementary to the search for new particles and symmetries in high-energy experiments. The close connections between the laws of microphysics, astrophysics and cosmology open further perspectives. This concerns, to mention some of them, properties of exotic nuclei and nuclear matter, and star evolution; the neutrino and the dark matter in the universe; relations between grand unification and evolution of the early universe. The International Symposium on Weak and Electromagnetic Interactions in Nuclei (W.E.LN. 1986)' held in Heidelberg 1-5 July 1986, in conjunction with the 600th anniversary of the University of Heidelberg, brought together experts in the fields of nuclear and particle physics, astrophysics and cosmol ogy.
