Dielectric resonances in disordered media
Laurent Raymond, Jean-Marie Laugier, Steffen Schäfer +1
Binary disordered systems are usually obtained by mixing two ingredients in variable proportions: conductor and insulator, or conductor and super-conductor. and are naturally model…
A Search for Anomalous Heavy-Flavor Quark Production in Association with W Bosons
D0 Collaboration, V. M. Abazov
We present a search for anomalous production of heavy-flavor quark jets in association with a W boson at the Fermilab Tevatron ppbar Collider. This search is conducted through an e…
L'algebre des symetries quantiques d'Ocneanu et la classification des systemes conformes a 2D
Gil Schieber
The partition functions of a 2D conformal system - the modular invariant one or the generalized ones, coming from the introduction of defect lines - are expressed in terms of a set…
On the rare decays
David Greynat
In this talk, we present our recent work on the $K\raπ\bar{l} l$ decays in a combined framework of chiral perturbation theory and Large-- QCD under the dominance of a minimal…
Explicit differential characterization of the Newtonian free particle system in m > 1 dependent variables
Joel Merker
In 1883, as an early result, Sophus Lie established an explicit necessary and sufficient condition for an analytic second order ordinary differential equation y_xx = F(x,y,y_x) to…
Measurement of the Top Quark Mass In All-Jet Events
D0 Collaboration, V. M. Abazov
We describe a measurement of the mass of the top quark from the purely hadronic decay modes of t-tbar pairs using all-jet data produced in p-pbar collisions at sqrt{s} = 1.8 TeV at…
Dynamic buckling and fragmentation in brittle rods
J. R. Gladden, N. Z. Handzy, A. Belmonte +1
We present experiments on the dynamic buckling and fragmentation of slender rods axially impacted by a projectile. By combining the results of Saint-Venant and elastic beam theory,…
Anharmonic oscillator driven by additive Ornstein-Uhlenbeck noise
Kirone Mallick, Philippe Marcq
We present an analytical study of a nonlinear oscillator subject to an additive Ornstein-Uhlenbeck noise. Known results are mainly perturbative and are restricted to the large diss…
Chiral perturbation theory confronted with experiment
Marc Knecht
The general framework and the present status of the low energy theory of the standard model are briefly reviewed. Recent applications to a few topic of interest for the determinati…
Shear effects on passive scalar spectra
A. Celani, M. Cencini, M. Vergassola +2
The effects of a large-scale shear on the energy spectrum of a passively advected scalar field are investigated. The shear is superimposed on a turbulent isotropic flow, yielding a…
A Search for the Flavor-Changing Neutral Current Decay B0_s -> mu^+mu^- in pp(bar) Collisions at \sqrt{s} = 1.96 TeV with the D0 Detector
D0 Collaboration, V. M. Abazov
We present the results of a search for the flavor-changing neutral current decay B0_s -> mu+ mu- using a data set with integrated luminosity of 240 pb^{-1} of pp(bar) collisions at…
Bose-Einstein Condensation in Geometrically Deformed Tubes
Pavel Exner, Valentin A. Zagrebnov
We show that Bose-Einstein condensate can be created in quasi-one-dimensional systems in a purely geometrical way, namely by bending or other suitable deformation of a tube.
Light hadron spectra and wave functions in quenched QCD with overlap quarks on a large lattice
Federico Berruto, Nicolas Garron, Christian Hoelbling +5
A simulation of quenched QCD with the overlap Dirac operator has been completed using 100 Wilson gauge configurations at beta=6 on an 18^3x64 lattice. We present results for meson…
Electroweak penguins and SUSY K^0-\bar K^0 mixing with Neuberger quarks
Federico Berruto, Nicolas Garron, Christian Hoelbling +5
We present results for Delta I=3/2 and Delta S=2 matrix elements relevant for CP violation in K->Pi Pi decays and for the K_S-K_L mass difference in the standard model and beyond.…
A comparative study of overlap and staggered fermions in QCD
S. Dürr, Ch. Hoelbling, U. Wenger
We perform a comparative study of the infrared properties of overlap and staggered fermions in QCD. We observe that the infrared spectrum of the APE/HYP improved staggered Dirac op…
Lattice diffusion and surface segregation of B during growth of SiGe heterostructures by molecular beam epitaxy: effect of Ge concentration and biaxial stress
A. Portavoce, P. Gas, I. Berbezier +3
Si1-xGex/Si1-yGey/Si(100) heterostructures grown by Molecular Beam Epitaxy (MBE) were used in order to study B surface segregation during growth and B lattice diffusion. Ge concent…
On quantum symmetries of the non--ADE graph F4
Robert Coquereaux, Esteban Isasi
We describe quantum symmetries associated with the F4 Dynkin diagram. Our study stems from an analysis of the (Ocneanu) modular splitting equation applied to a partition function w…
Measurement of the B^0_s lifetime in the exclusive decay channel B^0_s -> J/psi phi
D0 Collaboration, V. M. Abazov
Using the exclusive decay B^0_s -> J/psi (mu+mu-) phi(K+K-), we report the most precise single measurement of the B^0_s lifetime. The data sample corresponds to an integrated lumin…

O. Le Fevre, L. Guzzo, B. Meneux +44
This paper presents the evolution of the clustering of the main population of galaxies from z=2.1 to z=0.2, from the first epoch VIMOS VLT Deep Survey (VVDS), a magnitude limited s…
Universality of residence-time distributions in non-adiabatic stochastic resonance
Nils Berglund, Barbara Gentz
We present mathematically rigorous expressions for the residence-time and first-passage-time distributions of a periodically forced Brownian particle in a bistable potential. For a…
A Hamiltonian system for interacting Benjamin-Feir resonances
Tounsia Benzekri, Cristel Chandre, Ricardo Lima +1
In this paper, we present a model describing the time evolution of two dimensional surface waves in gravity and infinite depth. The model of six interacting modes derives from the…
Probing Dark Energy with Supernovae : a concordant or a convergent model?
J. -M. Virey, A. Ealet, C. Tao +4
We present a revised interpretation of recent analysis of supernovae data. We evaluate the effect of the priors on the extraction of the dark energy equation of state. We find that…
On the stochastic pendulum with Ornstein-Uhlenbeck noise
