Curved Flats and Isothermic Surfaces

F. Burstall, U. Hertrich-Jeromin, F. Pedit +1

We show how pairs of isothermic surfaces are given by curved flats in a pseudo Riemannian symmetric space and vice versa. Calapso's fourth order partial differential equation is de…

Constructing CP-Odd Observables

G. Valencia

In these lectures we review the general features necessary to construct $\cp$ odd observables and study illustrative examples. We present in some detail the case of $\cp$ violation…

Polarized Bhabha Scattering and a Precision Measurement of the Electron Neutral Current Couplings

the SLD Collaboration

We present the first measurement of the left-right asymmetry in Bhabha scattering with a polarized electron beam. The effective electron vector and axial vector couplings to the Z0…

FeII and FeI emission in IRAS 07598+6508 and PHL 1092

John Kwan, Fu-zhen Cheng, Li-Zhi Fang +2

One of the puzzles in understanding the spectra of active galactic nuclei (AGN) is the origin of the FeII emission. FeI emission, if present, will help reveal the physical conditio…

Restricted routing and wide diameter of the cycle prefix network

William Y. C. Chen, Vance Faber, Emanuel Knill

The cycle prefix network is a Cayley coset digraph based on sequences over an alphabet which has been proposed as a vertex symmetric communication network. This network has been sh…

Symmetry Tests and Standard Model Backgrounds

Barry R. Holstein

Symmetry tests provide an important probe for the structure of elementary particle interactions and for the validity of the standard model. However, it is pointed out that in the i…

NN,NΔCouplings and the Quark Model

Thomas R. Hemmert, Barry R. Holstein, Nimai C. Mukhopadhyay

We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector and strong NN and NΔcouplings, and demonstrate that the experimental NΔvalue i…

Uncertainties from Long Range Effects in $B \to K^* γ

Eugene Golowich, Sandip Pakvasa

We reconsider the `long-range' component of the radiative transition . A careful analysis of the vector dominance amplitude is carried out, w…

The Moduli Space of Complete Embedded Constant Mean Curvature Surfaces

Rob Kusner, Rafe Mazzeo, Daniel Pollack

We examine the space of surfaces in $\RR^{3}$ which are complete, properly embedded and have nonzero constant mean curvature. These surfaces are noncompact provided we exclude the…

Reanalysis of the decay K_L -> pi0 e+ e-

John F. Donoghue, Fabrizio Gabbiani

The decay K_L -> pi0 e+ e- is being searched for as a signal of direct Delta S = 1 CP violation. We provide a thorough updating of the analysis of the three components of the decay…

Universe Reheating after Inflation

Y. Shtanov, J. Traschen, R. Brandenberger

We study the problem of scalar particle production after inflation by a rapidly oscillating inflaton field. We use the framework of the chaotic inflation scenario with quartic and…

Supersymmetry and Stationary Solutions in Dilaton-Axion Gravity

Renata Kallosh, David Kastor, Tomas Ortin +1

New stationary solutions of -dimensional dilaton-axion gravity are presented, which correspond to the charged Taub-NUT and Israel-Wilson-Perjes (IWP) solutions of Einstein-Maxwe…

Corpus-Driven Knowledge Acquisition for Discourse Analysis

Stephen Soderland, Wendy Lehnert

The availability of large on-line text corpora provides a natural and promising bridge between the worlds of natural language processing (NLP) and machine learning (ML). In recent…

General relativity as an effective field theory: The leading quantum corrections

John F. Donoghue

I describe the treatment of gravity as a quantum effective field theory. This allows a natural separation of the (known) low energy quantum effects from the (unknown) high energy c…

Precise Measurement of the Left-Right Cross Section Asymmetry in Boson Production by $\ee$ Collisions

The SLD Collaboration

We present a precise measurement of the left-right cross section asymmetry () for boson production by $\ee$ collisions. The measurement was performed at a center-of-mas…

Computing Multidimensional Residues

Eduardo Cattani, Alicia Dickenstein, Bernd Sturmfels

Given n polynomials in n variables with a finite number of complex roots, for any of their roots there is a local residue operator assigning a complex number to any polynomial. Thi…

Adiabatic Invariants in Stellar Dynamics: III. Application to Globular Cluster Evolution

Martin D. Weinberg

The previous two companion papers demonstrate that slowly varying perturbations do not result in adiabatic cutoffs and provide a formalism for computing the long-term effects of ti…

Adiabatic Invariants in Stellar Dynamics: II. Gravitational shocking

Martin D. Weinberg

A new theory of gravitational shocking based on time-dependent perturbation theory shows that the changes in energy and angular momentum due to a slowly varying disturbance are not…

Adiabatic Invariants in Stellar Dynamics: I. Basic concepts

Martin D. Weinberg

The adiabatic criterion, widely used in astronomical dynamics, is based on the harmonic oscillator. It asserts that the change in action under a slowly varying perturbation is expo…
