Calogero-Moser systems and Hitchin systems
J. C. Hurtubise, E. Markman
We exhibit the elliptic Calogero-Moser system as a Hitchin system of G-principal Higgs pairs. The group G, though naturally associated to any root system, is not semi-simple. We th…
On Bose-Einstein condensate inside moving exciton-phonon droplets
D. Roubtsov, Y. Lepine, I. Loutsenko
We explore a nonlinear field model to describe the interplay between the ability of excitons to be Bose condensed and their interaction with other modes of a crystal. We apply our…
A Proof of the Security of Quantum Key Distribution
Eli Biham, Michel Boyer, P. Oscar Boykin +2
We prove the security of quantum key distribution against the most general attacks which can be performed on the channel, by an eavesdropper who has unlimited computation abilities…
Diffusion of gold nanoclusters on graphite
L. J. Lewis, P. Jensen, N. Combe +1
We present a detailed molecular-dynamics study of the diffusion and coalescence of large (249-atom) gold clusters on graphite surfaces. The diffusivity of monoclusters is found to…
Security Aspects of Practical Quantum Cryptography
Gilles Brassard, Norbert Lütkenhaus, Tal Mor +1
The use of quantum bits (qubits) in cryptography holds the promise of secure cryptographic quantum key distribution schemes. Unfortunately, the implemented schemes can be totally i…
Accurate Parameters of the Mass Distribution in Spiral Galaxies: 1. Fabry - Perot Observations of NGC 5585
Sebastien Blais-Ouellette, Claude Carignan, Philippe Amram +1
Using the example of the Sd galaxy NGC 5585, it is shown that high resolution 2-D HII kinematical data are necessary to determine accurately the parameters of the mass distribution…
Measurement of the W+W-gamma Cross-section and First direct Limits on Anomalous Electroweak Quartic Gauge Couplings
The OPAL collaboration, G. Abbiendi
A study of W+W- events accompanied by hard photon radiation produced in e+e- collisions at LEP is presented. Events consistent with two on-shell W-bosons and an isolated photon are…
The Star Formation History of the Starburst Region NGC 2363 and its Surroundings
L. Drissen, J. -R. Roy, C. Robert +2
We present HST optical images and UV spectra, as well as ground-based near-infrared images of the high surface brightness giant HII region NGC 2363 (NGC 2366-I) and its surrounding…
Bosons in a Lattice: Exciton-Phonon Condensate in Cu2O
D. Roubtsov, Y. Lepine
We explore a nonlinear field model to describe the interplay between the ability of excitons to be Bose-condensed and their interaction with other modes of a crystal. We apply our…
Soliton Solutions of Integrable Hierarchies and Coulomb Plasmas
Igor Loutsenko, Vyacheslav Spiridonov
Some direct relations between soliton solutions of integrable hierarchies and thermodynamical quantities of the Coulomb plasmas on the plane are revealed. We find that certain soli…
B-Decay CP Asymmetries, Discrete Ambiguities and New Physics
B. Kayser, D. London
The first measurements of CP violation in the system will likely probe , and . Assuming that the CP angles , and are the interior angles…
Scaling violations: Connections between elastic and inelastic hadron scattering in a geometrical approach
P. C. Beggio, M. J. Menon, P. Valin
Starting from a short range expansion of the inelastic overlap function, capable of describing quite well the elastic pp and scattering data, we obtain extensions to the…
Diffusion of hydrogen in crystalline silicon
Sabrina Bedard, Laurent J. Lewis
The coefficient of diffusion of hydrogen in crystalline silicon is calculated using tight-binding molecular dynamics. Our results are in good quantitative agreement with an earlier…
Multi-photon production in e+e- collisions at sqrt(s)= 189 geV
The OPAL collaboration, G. Abbiendi
The process e+e- to 2 (or 3) gammas is studied using data recorded with the OPAL detector at LEP. The data sample taken at a centre-of-mass energy of 189 GeV corresponds to a total…
Search for Higgs Bosons and Other Massive States decaying into two Photons in e+e- Collisions at 189 GeV
The OPAL collaboration, G. Abbiendi et al
A search is described for the generic process e+e- to X Y, where X is a neutral heavy scalar boson decaying into a pair of photons, and Y is a neutral heavy boson (scalar or vector…
An Investigation of the Large-scale Variability of the Apparently Single Wolf-Rayet Star WR 1
T. Morel, L. N. Georgiev, Y. Grosdidier +3
In recent years, much studies have focused on determining the origin of the large-scale line-profile and/or photometric patterns of variability displayed by some apparently single…
Looking for New Physics in Bd-Bd(bar) Mixing
D. London
There are variety of methods which directly test for the presence of new physics in the b -> s flavour-changing neutral current (FCNC), but none which cleanly probe new physics in…
Precision Flavour Physics and Supersymmetry
Ahmed Ali, David London
We review the salient features of a comparative study of the profile of the CKM unitarity triangle, and the resulting CP-violating phases , and in B decays, in the stand…
On certain classes of solutions of the Weierstrass-Enneper system inducing constant mean curvature surfaces
Paul Bracken, Alfred M. Grundland
Analysis of the generalized Weierstrass-Enneper system includes the estimation of the degree of indeterminancy of the general analytic solution and the discussion of the boundary v…
Quantum cryptography via parametric downconversion
Gilles Brassard, Tal Mor, Barry C. Sanders
The use of quantum bits (qubits) in cryptography holds the promise of secure cryptographic quantum key distribution schemes. It is based usually on single-photon polarization state…
