A Comparison of Clover and Wilson Spectroscopy in the Presence of Dynamical Quarks
Sara Collins, Robert G. Edwards, Urs M. Heller +1
We present preliminary results of light hadron spectroscopy using valence, tadpole-improved, Clover fermions on an ensemble of gauge configurations generated with 2 flavors of stag…
Upsilon and J/Psi Spectroscopy Using Clover Fermions in the Presence of Dynamical Quarks
Sara Collins, Robert G. Edwards, Urs M. Heller +1
We calculate spin averaged splittings in the bottomonium and charmonium systems using the clover action. We compare static and kinetic masses of heavy-heavy and heavy-light mesons…
Search for Right-Handed Bosons and Heavy in Collisions at 1.8 TeV

We report on a search for right-handed bosons (). We used data collected with the DØ detector at the Fermilab Tevatron collider at 1.8 TeV to search f…
Signals for Minimal Supergravity at the CERN Large Hadron Collider II: Multilepton Channels
Howard Baer, Chih-hao Chen, Frank Paige +1
We use ISAJET to perform a detailed study of the multilepton signals expected from cascade decays of supersymmetric particle produced at the CERN LHC. Our analysis is performed wit…
Analytical and computational study of magnetization switching in kinetic Ising systems with demagnetizing fields
Howard L. Richards, Mark A. Novotny, Per Arne Rikvold
An important aspect of real ferromagnetic particles is the demagnetizing field resulting from magnetostatic dipole-dipole interaction, which causes large particles to break up into…

A measurement of inclusive charged particle distributions in deep inelastic scattering for centre-of-mass energies ~GeV and momentum transfer squared $10<…
Superconductivity in the Cuprates as a Consequence of Antiferromagnetism and a Large Hole Density of States
E. Dagotto, A. Nazarenko, A. Moreo +1
We briefly review a theory for the cuprates that has been recently proposed based on the movement and interaction of holes in antiferromagnetic (AF) backgrounds. A robust peak in t…
Heavy Quasiparticles in the Anderson Lattice Model
K. Tsutsui, Y. Ohta, R. Eder +3
An exact-diagonalization technique on small clusters is used to study the dynamics of the one-dimensional symmetric Anderson lattice model. Our calculated excitation spectra reprod…
Large Transverse Momentum Jet Production and the Gluon Distribution Inside the Proton
J. Huston, E. Kovacs, S. Kuhlmann +4
The CDF experiment has reported an excess of high- jets compared to previous next-to-leading order QCD expectations. Before attributing this to new physics effects, we investi…
