Color Transparency and the Vanishing Deuterium Shadow
L. L. Frankfurt, W. R. Greenberg, G. A. Miller +2
We find that the final state interactions in the amplitude depend strongly on the final momentum of the spectator nucleon. This means that color transparency effects ca…
New Corrections of Order to -Levels of Two-Body Systems
Michael I. Eides, Howard Grotch
New corrections to the energy of -levels of positronium of order which are as large as several hundred kilohertz are obtained. A new recoil correction of order $α(Zα)^5(m…
Coherent State Transforms for Spaces of Connections
Abhay Ashtekar, Jerzy Lewandowski, Donald Marolf +2
The Segal-Bargmann transform plays an important role in quantum theories of linear fields. Recently, Hall obtained a non-linear analog of this transform for quantum mechanics on Li…
Differential Geometry on the Space of Connections via Graphs and Projective Limits
Abhay Ashtekar, Jerzy Lewandowski
In a quantum mechanical treatment of gauge theories (including general relativity), one is led to consider a certain completion, $\agb$, of the space $\ag$ of gauge equivalent conn…
Gravity and Geometric Phases
A. Corichi, M. Pierri
The behavior of a quantum test particle satisfying the Klein-Gordon equation in a certain class of 4 dimensional stationary space-times is examined. In a space-time of a spinning c…
On the validity of mean-field amplitude equations for counterpropagating wavetrains
R. D. Pierce, C. E. Wayne
We rigorously establish the validity of the equations describing the evolution of one-dimensional long wavelength modulations of counterpropagating wavetrains for a hyperbolic mode…
Real Space Renormalization Group for Langevin Dynamics in Absence of Translational Invariance
Achille Giacometti, Amos Maritan, Flavio Toigo +1
A novel exact dynamical real space renormalization group for a Langevin equation derivable from a Euclidean Gaussian action is presented. It is demonstrated rigorously that an alge…
Aspects of four-jet production in polarized proton-proton collisions
S. P. Fraser, S. T. Fraser, R. W. Robinett
We examine the intrinsic spin-dependence of the dominant subprocess contribution to four-jet production in polarized proton-proton collisions using helicity a…
Projective Techniques and Functional Integration
Abhay Ashtekar, Jerzy Lewandowski
A general framework for integration over certain infinite dimensional spaces is first developed using projective limits of a projective family of compact Hausdorff spaces. The proc…
Spectral Classification of Galaxies: An Orthogonal Approach
A. J. Connolly, A. S. Szalay, M. A. Bershady +2
Classification of galaxy spectral energy distributions in terms of orthogonal basis functions provides an objective means of estimating the number of significant spectral component…
Solving the Constraints of General Relativity
J. Fernando Barbero
I show in this letter that it is possible to solve some of the constraints of the -ADM formalism for general relativity by using an approach similar to the one introduced by…
Discreteness of area and volume in quantum gravity
Carlo Rovelli, Lee Smolin
We study the operator that corresponds to the measurement of volume, in non-perturbative quantum gravity, and we compute its spectrum. The operator is constructed in the loop repre…
Action and Hamiltonian for eternal black holes
Valeri Frolov, Erik A. Martinez
We present the Hamiltonian, quasilocal energy, and angular momentum for a spacetime region spatially bounded by two timelike surfaces. The results are applied to the particular cas…
Asymptotic Symmetry Groups of Long-Ranged Gauge Configurations
Domenico Giulini
We make some general remarks on long-ranged configurations in gauge or diffeomorphism invariant theories where the fields are allowed to assume some non vanishing values at spatial…
Instanton-induced production of QCD jets
I. I. Balitsky, V. M. Braun
We consider the instanton contributions for the production of a gluon jet with large transverse momentum in QCD. We find that Mueller's corrections corresponding to the rescatterin…
Real Ashtekar Variables for Lorentzian Signature Space-times
J. Fernando Barbero
I suggest in this letter a new strategy to attack the problem of the reality conditions in the Ashtekar approach to classical and quantum general relativity. By writing a modified…
Reality Conditions and Ashtekar Variables: a Different Perspective
J. Fernando Barbero
We give in this paper a modified self-dual action that leads to the -ADM formalism without having to face the difficult second class constraints present in other approaches…
Conservation Laws in the Quantum Mechanics of Closed Systems
James B. Hartle, Raymond Laflamme, Donald Marolf
We investigate conservation laws in the quantum mechanics of closed systems. We review an argument showing that exact decoherence implies the exact conservation of quantities that…
Bounds on the decay of the auto-correlation in phase ordering dynamics
Chuck Yeung, Madan Rao, Rashmi Desai
We obtain bounds on the decay exponent lambda of the autocorrelation function in phase ordering dynamics. For non-conserved order parameter, we recover the Fisher and Huse inequali…
Is there a connection between no-hair behavior and universality in gravitational collapse?
Jorge Pullin
We apply linear perturbation theory to the study of the universality and criticality first observed by Choptuik in gravitational collapse. Since these are essentially nonlinear phe…
Instanton-induced production of jets with large transverse momentum in QCD
I. I. Balitsky, V. M. Braun
We consider the instanton-induced cross section for production of a gluon jet with large transverse momentum in QCD and point out that Mueller's corrections corresponding to the re…
Small forcings and Cohen reals
Jindřich Zapletal
We prove it consistent relative to ZFC that all nontrivial forcings of size add a Cohen real.
OTTER Experiments in a System of Combinatory Logic
Thomas Jech
This paper describes some experiments involving the automated theorem-proving program OTTER in the system TRC of illative combinatory logic. We show how OTTER can be steered to fin…
Proper Time Formalism, Gauge Invariance and the Effects of a Finite World Sheet Cutoff in String Theory
B. Sathiapalan
We discuss the issue of going off-shell in the proper time formalism. This is done by keeping a finite world sheet cutoff. We construct one example of an off-shell covariant Klein…
