Connection between Tomboulis vortices and projection vortices

A. Alexandru, Richard W. Haymaker

By using the freedom of picking a representative we explore connections between the Tomboulis SO(3)xZ(2) form of the partition function and the SU(2) form. We are able to express t…

The Continuous Wavelet Transform and Symmetric Spaces

R. Fabec, G. Olafsson

The continuous wavelet transform has become a widely used tool in applied science during the last decade. In this article we discuss some generalizations coming from actions of clo…

A finite spin-foam-based theory of three and four dimensional quantum gravity

Rodolfo Gambini, Jorge Pullin

Starting from Ooguri's construction for theory in three (and four) dimensions, we show how to construct a well defined theory with an infinite number of degrees of freedom. Th…

Search for R-parity Violating Decays of Supersymmetric Particles in e+e- Collisions at LEP

L3 Collaboration

A search, in e^+e^- collisions, for chargino, neutralino, scalar lepton and scalar quark pair-production is performed, without assuming R-parity conservation in decays, in the case…

A mixed-mode shell-model theory for nuclear structure studies

V. G. Gueorguiev, W. E. Ormand, C. W. Johnson +1

We introduce a shell-model theory that combines traditional spherical states, which yield a diagonal representation of the usual single-particle interaction, with collective config…

Close limit evolution of Kerr-Schild type initial data for binary black holes

Olivier Sarbach, Manuel Tiglio, Jorge Pullin

We evolve the binary black hole initial data family proposed by Bishop {\em et al.} in the limit in which the black holes are close to each other. We present an exact solution of t…

Induced Lorentz-Violating Chern-Simons Term in QED: Uncovering Short Distance Interaction Terms in the Effective Lagrangian without the Shadow of Regularization

Lai-Him Chan

We show that the correctly evaluated effective Lagrangian should include short-distance interaction terms which have been avoided under the protection of usual regularization and m…

An Adaptive, Kink-Based Approach to Path Integral Calculations

Randall W. Hall

A kink-based expression for the canonical partition function is developed using Feynman's path integral formulation of quantum mechanics and a discrete basis set. The approach is e…

Progress on stochastic background search codes for LIGO

John T. Whelan, Warren G. Anderson, Martha Casquette +7

One of the types of signals for which the LIGO interferometric gravitational wave detectors will search is a stochastic background of gravitational radiation. We review the techniq…

On representations and K-theory of the braid groups

Alejandro Adem, Daniel C. Cohen, Frederick R. Cohen

Let G be the fundamental group of the complement of a K(G,1) hyperplane arrangement (such as Artin's pure braid group) or more generally a homologically toroidal group (as defined…
