Loop Variables and Gauge Invariant Interactions of Massive Modes in String Theory
B. Sathiapalan
The loop variable approach used earlier to obtain free equations of motion for the massive modes of the open string, is generalized to include interaction terms. These terms, which…
The geometry of quantum spin networks
Roumen Borissov, Seth Major, Lee Smolin
The discrete picture of geometry arising from the loop representation of quantum gravity can be extended by a quantum deformation. The operators for area and volume defined in the…
Quantum deformation of quantum gravity
Seth Major, Lee Smolin
We describe a deformation of the observable algebra of quantum gravity in which the loop algebra is extended to framed loops. This allows an alternative nonperturbative quantizatio…
Inclusive Charged Particle Distributions in Deep Inelastic Scattering Events at HERA
The ZEUS Collaboration
A measurement of inclusive charged particle distributions in deep inelastic scattering for centre-of-mass energies ~GeV and momentum transfer squared $10<…
On Covariant Derivatives and Gauge Invariance in the Proper Time Formalism for String Theory
B. Sathiapalan
It is shown that the idea of ``minimal'' coupling to gauge fields can be conveniently implemented in the proper time formalism by identifying the equivalent of a ``covariant deriva…
An axiomatic approach to quantum gauge field theory
Thomas Thiemann
In the present article we display a new constructive quantum field theory approach to quantum gauge field theory, utilizing the recent progress in the integration theory on the mod…
An account of transforms on \bar {{\cal A}/{\cal G}}
Thomas Thiemann
In this article we summarize and describe the recently found transforms for theories of connections modulo gauge transformations associated with compact gauge groups. Specifically,…
Topological Phase Transition in the Quantum Hall Effect
I. A. McDonald, F. D. M. Haldane
The double layer fractional quantum Hall system is studied using the edge state formalism and finite-size diagonalization subject to periodic boundary conditions. Transitio…
Exact solutions for null fluid collapse
Viqar Husain
Exact non-static spherically symmetric solutions of the Einstein equations for a null fluid source with pressure and density related by are given. The metr…
The Nucleon's Antiquark Sea: A Virtual Meson Cloud or Gluons?
W. Koepf, L. L. Frankfurt, M. Strikman
We study the possible contribution of the nucleon's virtual meson cloud to the sea quark distribution as observed in deep inelastic lepton scattering. We adjust the meson-nucleon c…
Power-law Distributions in the Kauffman Net
Amartya Bhattacharjya, Shoudan Liang
Kauffman net is a dynamical system of logical variables receiving two random inputs and each randomly assigned a boolean function. We show that the attractor and transient lengths…
Minisuperspace Examples of Quantization Using Canonical Variables of the Ashtekar Type: Structure and Solutions
J. Fernando Barbero, Michael P. Ryan
The Ashtekar variables have been use to find a number of exact solutions in quantum gravity and quantum cosmology. We investigate the origin of these solutions in the context of a…
Nuclear phenomena at HERA energies
Leonid Frankfurt, Mark Strikman
We argue that current data on nuclear shadowing confirm expectations of the color singlet models of nuclear shadowing. We demonstrate that unitarity constrains require nuclear shad…
QCD and Diffraction in DIS
Leonid Frankfurt, Mark Strikman
Coherence phenomena, and the non-universality of parton structure of the effective Pomeron are explained. New hard phenomena directly calculable in QCD such as diffractive electrop…
Polarized Beam Jets
John Collins
Handedness and a left-right asymmetry have been proposed as methods of probing the polarization of hard jets. If the analyzing powers for these observables are substantial they wou…
Cosmic Microwave Background Anisotropies from the Rees-Sciama Effect in Universes
Robin Tuluie, Pablo Laguna, Peter Anninos
We investigate the imprint of nonlinear matter condensations on the Cosmic Microwave Background (CMB) in cold dark matter (CDM) model universes. We consider simulation do…
The Problem Of Scales: Renormalization and All That
John Collins
I explain the methods that are used in field theory for problems involving typical momenta on two or more widely disparate scales. The principal topics are: (a) renormalization, wh…
Second order perturbations of a Schwarzschild black hole
Reinaldo Gleiser, Oscar Nicasio, Richard Price +1
We study the even-parity perturbations of a Schwarzschild black hole to second order. The Einstein equations can be reduced to a single linear wave equation with a potenti…
Double Pomeron Jet Cross Sections
Arjun Berera, John C. Collins
We treat hadron-hadron collisions where the final state is kinematically of the kind associated with double-pomeron-exchange (DPE) and has large transverse momentum jets. We show t…
Warm Inflation
Arjun Berera
Assuming a first order phase transition during inflation, a model scenario is described which does not require a tiny coupling constant. Thermal equilibrium is closely maintained a…
Behavior of Diffractive Parton Distribution Functions
Arjun Berera, Davison E. Soper
Diffractive parton distribution functions give the probability to find a parton in a hadron if the hadron is diffractively scattered. We provide an operator definition of these fun…
The Apparently Normal Galaxy Hosts for Two Luminous Quasars
John N. Bahcall, Sofia Kirhakos, Donald P. Schneider
HST images (with WFPC2) of PHL~909\ () and PG~0052251\ () show that these luminous radio-quiet quasars each occur in an apparently normal host galaxy. The…
HST and MERLIN Observations of the Jet in 3C273
J. N. Bahcall, S. Kirhakos, D. P. Schneider +5
We present red and blue images of the jet of the quasar 3C273 obtained with the WFPC2 on the Hubble Space Telescope as well as a new radio map made with the MERLIN array. The image…
Chern-Simons Duality and the Quantum Hall Effect
A. P. Balachandran, L. Chandar, B. Sathiapalan
In previous work on the quantum Hall effect on an annulus, we used duality transformations on the action describing edge excitations to generate the Haldane hierar…
