Search for Right-Handed $W$ Bosons and Heavy $W^{'}$ in $p p ˉ$ Collisions at $s =$ 1.8 TeV

S. Abachi

We report on a search for right-handed $W$ bosons ( $W_{R}$ ). We used data collected with the DØ detector at the Fermilab Tevatron $p p ˉ$ collider at $s =$ 1.8 TeV to search f…

Search for $W_{1} Z_{2}$ Production via Trilepton Final States in $p p ˉ$ collisions at $s = 1.8$ TeV

S. Abachi

We have searched for associated production of the lightest chargino, $W_{1}$ , and next-to-lightest neutralino, $Z_{2}$ , of the Minimal Supersymmetric Standard M…

Elastic String in a Random Medium

Hernán A. Makse, Albert-László Barabási, H. Eugene Stanley

We consider a one dimensional elastic string as a set of massless beads interacting through springs characterized by anisotropic elastic constants. The string, driven by an externa…

Method for Generating Long-Range Correlations for Large Systems

Hernán A. Makse, Shlomo Havlin, Moshe Schwartz +1

We propose a new method to generate a sequence of random numbers with long-range power-law correlations that overcomes known difficulties associated with large systems. The new met…

Direct Tests of Dynamical Electroweak Symmetry Breaking

E. H. Simmons, R. S. Chivukula, J. Terning

We review the connection between $m_{t}$ and the $Z b b ˉ$ vertex in ETC models and discuss the resulting experimental constraint on models with weak-singlet ETC bosons. We mention…

Measurement of the Average $B$ -Hadron Lifetime in $Z^{0}$ Decays

The SLD Collaboration

We report a measurement of the average $B$ -hadron lifetime using data collected with the SLD detector at the SLC in 1993. An inclusive analysis selected three-dimensional vertices…

Coarsening and persistence in the voter model

E. Ben-Naim, L. Frachebourg, P. L. Krapivsky

We investigate coarsening and persistence in the voter model by introducing the quantity $P_{n} (t)$ , defined as the fraction of voters who changed their opinion n times up to time t.…

Stochastic Model for Surface Erosion Via Ion-Sputtering: Dynamical Evolution from Ripple Morphology to Rough Morphology

Rodolfo Cuerno, Hernan A. Makse, Silvina Tomassone +2

Surfaces eroded by ion-sputtering are sometimes observed to develop morphologies which are either ripple (periodic), or rough (non-periodic). We introduce a discrete stochastic mod…

Threshhold Singularities and the Magnetic Mass in Hot QCD

R. Jackiw, So-Young Pi

We discuss the recently devised one-loop gap equation for the magnetic mass of hot QCD. An alternative, and one would hope equivalent, gap equation is presented, which however show…

Test of CPT Symmetry and Quantum Mechanics with Experimental data from CPLEAR

R. Adler, etal, J. Ellis +3

We use fits to recent published CPLEAR data on neutral kaon decays to $π^{+} π^{-}$ and $π e ν$ to constrain the CPT--violation parameters appearing in a formulation of the neutral kaon s…

The Effects of Electron-Electron Interactions on the Integer Quantum Hall Transitions

Dung-Hai Lee, Ziqiang Wang

We study the effects of electron-electron interaction on the critical properties of the plateau transitions in the {\it integer} quantum Hall effect. We find the renormalization gr…

A fractal model for the first stages of thin film growth

Pablo Jensen, Albert-László Barabási, Hernán Larralde +2

In this paper we briefly review a model that describes the diffusion-controlled aggregation exhibited by particles as they are deposited on a surface. This model allows to understa…

Probing the halo of Centaurus A: a merger dynamical model for the PN population

A. Mathieu, H. Dejonghe, X. Hui

Photometry and kinematics of the giant elliptical galaxy NGC~5128 (Centaurus~A) based on planetary nebulae observations (Hui~\etal 1995) are used to build dynamical models which al…

Spinodal decomposition in fluids: diffusive, viscous and inertial regimes

Turab Lookman, Yanan Wu, Francis Alexander +1

Using a Langevin description of spinodal decomposition in fluids, we examine domain growth in the diffusive, viscous and inertial regimes. In the framework of this model, numerical…

Domain Wall Fermions and the Eta Invariant

David B. Kaplan, Martin Schmaltz

We extend work by Callan and Harvey and show how the phase of the chiral fermion determinant in four dimensions is reproduced by zeromodes bound to a domain wall in five dimensions…

Gluino mass from dynamical supersymmetry breaking

Bogdan A. Dobrescu

We present a new mechanism for gluino mass generation in models of dynamical supersymmetry breaking. The mechanism requires two colored chiral superfields which feel a nonabelian g…

Testing Extended Technicolor With $R_{b}$

E. H. Simmons, R. S. Chivukula, J. Terning

We review the connection between $m_{t}$ and the $Z b b ˉ$ vertex in ETC models and demonstrate the power of the resulting experimental constraint on models with weak-singlet ETC bo…

Self-Organized Branching Processes: A Mean-Field Theory for Avalanches

Stefano Zapperi, Kent Baekgaard Lauritsen, H. Eugene Stanley

We discuss mean-field theories for self-organized criticality and the connection with the general theory of branching processes. We point out that the nature of the self-organizati…

Dynamical Electroweak Symmetry Breaking and the Top Quark

R. Sekhar Chivukula

In this talk I discuss theories of dynamical electroweak symmetry breaking, with emphasis on the implications of a heavy top-quark on the weak-interaction $ρ$ parameter.

Annihilation of Charged Particles

I. Ispolatov, P. Krapivsky

The kinetics of irreversible annihilation of charged particles performing overdamped motion induced by long-range interaction force, $F (r) \sim r^{- λ}$ , is investigated. The system…

Borderline Aggregation Kinetics in ``Dry'' and ``Wet'' Environments

Paul. L. Krapivsky, Sidney Redner

We investigate the kinetics of constant-kernel aggregation which is augmented by either: (a) evaporation of monomers from finite-mass clusters, or (b) continuous cluster growth --…
