OO design and implementation: Java and Java analysis studio
We present an overview of the Java language, Java virtual machine, and the large set of standard libraries and extensions available for Java, and provide a discussion of issues that effect Java performance. This is followed by an introduction to Java Analysis Studio (JAS), a tool written in Java, and in which Java is the language used to perform data analysis. We will also explore how OO techniques have been used to built a system from modular components including visualization, fitting and data-access components that can be used together, or on their own.

title: Observations of Milky Way Dwarf Spheroidal galaxies with the Fermi-LAT detector and constraints on Dark Matter models
abstract: We report on the observations of 14 dwarf spheroidal galaxie s with theFermi Gamma-Ray Space Telescope taken during the first 11 months of survey mod e operations. TheFermi telescope, which is conducting an all-sky γ-ray survey in the 20 MeV to>300 GeV energy range, provides a new opportunity to test particle dark matter mode ls through the expected γ-ray emission produced by pair annihilation of weakly interacting ma ssive particles (WIMPs).

title: Java Analysis Studio
abstract: Java Analysis Studio is a desktop data analysis application aimed primarily at offline analysis of high-energy physics data. The goal is to make the application independent of any particular data format, so that it can be used to analyze data from any experiment. The application features a rich graphical user interface (GUI) aimed at making the program easy to learn and use, but which at the same time allows the user to perform arbitrarily complex data analysis tasks by writing analysis modules in Java. The application can be used either as a standalone application, or as a client for a remote Java Data Server. The client-server mechanism is targeted particularly at allowing remote users to access large data samples stored on a central data center in a natural and efficient way.

title: A Measurement of the left-right, forward - backward asymmetry for charm quarks using D*+ and D+ mesons
abstract: Longitudinal polarization of the SLC e{sup {minus}} beam allows a direct measurement of the left-right, forward-backward asymmetry of c-quarks to be made with the SLD. Events from Z{sup 0} {yields} c{bar c} are tagged using fully and partially reconstructed decays of D{sup *+} mesons, and fully reconstructed decays of D{sup +} mesons. The authors measure A{sub c} = 0.77 {+-} 0.22(stat.) {+-} 0.10(syst.).

title: Symmetry tests in polarized Z0 decays to b anti-b g

title: Direct measurement of parity violation in the coupling of Z(0) bosons to b quarks using a mass tag and momentum-weighted track charge
abstract: We present a direct measurement of the parity-violation parameter A{sub b} using a self-calibrating track-charge technique. In the SLAC Linear Collider Large Detector (SLD) experiment we observe hadronic decays of Z{sup 0} bosons produced in collisions between longitudinally polarized electrons and unpolarized positrons at the SLAC Linear Collider. A sample of b{bar b} events is selected using the topologically reconstructed mass of B hadrons. From our 1993{endash}1995 sample of approximately 150000 hadronic Z{sup 0} decays, we obtain A{sub b}=0.911{plus_minus}0.045(stat) {plus_minus}0.045(syst) . {copyright} {ital 1998}

title: Realistic pseudoscalar-vector chiral Lagrangian and its soliton excitations.
abstract: A reasonable low-energy chiral Lagrangian of vectors and pseudoscalars involves three a priori unknown coefficients for terms proportional to the Levi-Civita symbol epsilon/sub ..mu..//sub ..nu..//sub ..cap alpha..//sub ..beta../. We argue that these cannot, from a theoretical standpoint, be reliably determined by consideration of electromagnetic processes. Hence we use purely strong-interaction processes which enable us to determine two out of three of these. We examine the nucleon as a soliton excitation in the model and find that adjustment of the third parameter does not greatly change the, in most respects accurate, description of the nucleon obtained in a previous treatment by Meissner, Kaiser, and Weise. The paper includes a new and careful formulation of the addition of electromagnetism to the full Lagrangian.

title: Bag formation in a chiral model.
abstract: We show that a bag can be automatically formed in a model where the Skyrme Lagrangian is modified to possess the correct QCD scaling behavior.

title: Low-energy technicolor Lagrangian with vector mesons.
abstract: We apply techniques used in QCD and the implied chiral symmetry to motivate a low-energy Lagrangian for technicolor theories. This allows one to cleanly introduce the gluon and the weak gauge bosons at the technifermion level. The Higgs mechanism and techni-vector-meson dominance are displayed. The effect of vector dominance on the {ital W} and {ital Z} masses, the techni-{omega} and techni-{rho} couplings, and the sizable enhancement by the latter on {ital W} and {ital Z} production are demonstrated. Differences between our results and some published results are discussed. The incorporation of extended technicolor interactions is also presented.

title: Strongly coupled quarks in the standard model.
abstract: For sufficiently strong Yukawa couplings the standard model goes over to the linear sigma model. We point out that the associated heavy quarks may behave like strongly interacting low-energy u and d quarks so one cannot argue that very-heavy-quark systems will provide an easy test of QCD. An upper-quark-mass bound of about 1.5 TeV is found. This should also apply to techniquarks.) Experimental confirmation of the scheme might come from the observation of very tightly bound baryons made from three heavy quarks.

title: Bag formation in the presence of vector mesons. II. Inclusion of scalars.
abstract: We construct an effective Lagrangian of pions, the vector mesons rho and ..omega.., as well as a scalar meson and a scalar glueball which incorporates chiral symmetry and the QCD trace anomaly. The scalar sector is set up so that it contains particles in a realistic mass range with physically narrow widths. We calculate static nucleon properties and demonstrate that shallow bags with typical confinement sizes of Rapprox.1/2 fm are favored by phenomenology.
