Using FU Orionis Outbursts to Constrain Self-Regulated Protostellar Disk Models

K. R. Bell, D. N. C. Lin

One dimensional, convective, vertical structure models and one dimensional, time dependent, radial diffusion models are combined to create a self-consistent picture in which FU~Ori…

Probability distributions for one component equations with multiplicative noise

J. M. Deutsch

Systems described by equations involving both multiplicative and additive noise are common in nature. Examples include convection of a passive scalar field, polymersin turbulent fl…

Monte Carlo study of a vortex glass model

J. D. Reger, A. P. Young

We describe results of Monte Carlo simulations on a model that seems to have the necessary ingredients to describe a disordered type-II superconductor in a magnetic field. We compu…

Dijet Production at Large Rapidity Intervals

Vittorio Del Duca, Carl R. Schmidt

We examine dijet production at large rapidity intervals at Tevatron energies, by using the theory of Lipatov and collaborators which resums the leading powers of the rapidity inter…

Non-Linear Clustering in the Cold+Hot Dark Matter Model

S. A. Bonometto, S. Borgani, S. Ghigna +2

We use high resolution PM N-body simulations to follow the development of non-linear clustering in a flat Universe, dominated by Cold + Hot Dark Matter (CHDM) with 60% of CDM, 30%…

Particle Astrophysics from the Particle Perspective

Michael Dine

In this talk I discuss several topics at the interface of particle physics and astrophysics/cosmology. These include the problem of dark matter and two popular dark matter candidat…

Vector Leptoquark Production at Hadron Colliders

J. Hewett, T. Rizzo, S. Pakvasa +2

We explore the production of vector leptoquarks () at the Tevatron, LHC, and SSC through both quark-antiquark and gluon fusion: . The cross sections are fou…

Detecting Technibaryon Dark Matter

John Bagnasco, Michael Dine, Scott Thomas

The technibaryon constitutes a possible dark matter candidate. Such a particle with electroweak quantum numbers is already nearly ruled out as the dominant component of the galacti…

A Family of Models for Spherical Stellar Systems

S. Tremaine. D. O. Richstone, Y. -I. Byun, A. Dressler +4

We describe a one-parameter family of models of stable spherical stellar systems in which the phase-space distribution function depends only on energy. The models have similar dens…

The superconductor-insulator transition in 2D dirty boson systems

M. Wallin, E. Sorensen, S. M. Girvin +1

Universal properties of the zero temperature superconductor-insulator transition in two-dimensional amorphous films are studied by extensive Monte Carlo simulations of bosons in a…

Counter-Evolution of Faint Field Galaxies

D. C. Koo, C. Gronwall, G. Bruzual

We adopt a new approach to explore the puzzling nature of faint blue field galaxies. Instead of assuming that the local luminosity function is well defined, we first determine whet…

The Renormalization-Group Improved Higgs Sector of the Minimal Supersymmetric Model

Howard E. Haber, Ralf Hempfling

In the minimal supersymmetric model (MSSM) all Higgs self-coupling parameters are related to gauge couplings at tree-level. Leading-logarithmic radiative corrections to these quant…

Fredholm Determinants, Differential Equations and Matrix Models

Craig A. Tracy, Harold Widom

Orthogonal polynomial random matrix models of NxN hermitian matrices lead to Fredholm determinants of integral operators with kernel of the form (phi(x) psi(y) - psi(x) phi(y))/x-y…

Discovering Supersymmetry with Like-sign Dileptons

R. Michael Barnett, John F. Gunion, Howard E. Haber

Supersymmetry may be discovered at hadron colliders by searching for events similar to the top quark signal of two isolated leptons. In the case of gluino production, the most dist…

Constraints on CP violation in the Higgs sector from the parameter

Alex Pomarol, Roberto Vega

We discuss the relation between the CP symmetry and the custodial symmetry in the Higgs sector. In particular, we show that CP violation in the Higgs-gauge sector is allowe…

Flavor Symmetries and The Problem of Squark Degeneracy

M. Dine, A. Kagan, R. G. Leigh

If supersymmetry exists at low energies, it is necessary to understand why the squark spectrum exhibits sufficient degeneracy to suppress flavor changing neutral currents. In this…

Dissipation Induced Instabilities

Anthony Bloch, P. S. Krishnaprasad, Jerrold E. Marsden +1

The main goal of this paper is to prove that if the energy-momentum (or energy-Casimir) method predicts formal instability of a relative equilibrium in a Hamiltonian system with sy…

Critical Exponents of the Three Dimensional Random Field Ising Model

Heiko Rieger, A. P. Young

The phase transition of the three--dimensional random field Ising model with a discrete () field distribution is investigated by extensive Monte Carlo simulations. Values of…

Level-Spacing Distributions and the Bessel Kernel

Craig A. Tracy, Harold Widom

The level spacing distributions which arise when one rescales the Laguerre or Jacobi ensembles of hermitian matrices is studied. These distributions are expressible in terms of a F…

Dynamical Supersymmetry Breaking at Low Energies

Michael Dine, Ann E. Nelson

Conventional approaches to supersymmetric model building suffer from several naturalness problems: they do not explain the large hierarchy between the weak scale and the Planck mas…

Supersymmetry and the Nelson-Barr Mechanism

M. Dine, A. Kagan, R. G. Leigh

One possible solution to the strong CP problem is that CP is an exact symmetry, spontaneously broken at some scale. Some years ago, Nelson and Barr suggested a mechanism for obtain…
