The ANTARES Optical Module
The ANTARES Collaboration
The ANTARES collaboration is building a deep sea neutrino telescope in the Mediterranean Sea. This detector will cover a sensitive area of typically 0.1 km-squared and will be equi…
Ornstein-Zernike Theory for the finite range Ising models above T_c
M. Campanino, D. Ioffe, Y. Velenik
We derive precise Ornstein-Zernike asymptotic formula for the decay of the two-point function in the general context of finite range Ising type models on Z^d. The proof relies in a…
Electrical Spin Injection in a Ferromagnetic / Tunnel Barrier/ Semiconductor Heterostructure
V. F. Motsnyi, V. I. Safarov, J. De Boeck +4
We demonstrate experimentally the electrical ballistic electron spin injection from a ferromagnetic metal / tunnel barrier contact into a semiconductor III-V heterostructure. We in…
A statistical approach for polarized parton distributions
C. Bourrely, J. Soffer, F. Buccella
A global next-to-leading order QCD analysis of unpolarized and polarized deep-inelastic scattering data is performed with parton distributions constructed in a statistical physical…
Spectral action beyond the standard model
Thomas Schucker, Sami Zouzou
We rehabilitate the M_1(C)+ M_2(C)+ M_3(C) model of electro-magnetic, weak and strong forces as an almost commutative geometry in the setting of the spectral action.
Regularity of quasi-stationary measures for simple exclusion in dimension d >= 5
Amine Asselah, Pablo A. Ferrari
We consider the symmetric simple exclusion process on Z^d, for d>= 5, and study the regularity of the quasi-stationary measures of the dynamics conditionned on not occupying the or…
The Inclusive Jet Cross Section in ppbar Collisions at sqrt{s}=1.8 TeV using the kT Algorithm
D0 Collaboration, V. M. Abazov
The central inclusive jet cross section has been measured using a successive-combination algorithm for reconstruction of jets. The measurement uses 87.3 pb^{-1} of data collected w…
A Search forthe Scalar Top Quark in Collisions at 1.8 TeV
D0 Collaboration, V. M. Abazov
We have performed a search for scalar top quark (stop) pair production in the inclusive electron-muon-missing transverse energy final state, using a sample of events co…
BRST operator for quantum Lie algebras and differential calculus on quantum groups
A. P. Isaev, O. V. Ogievetsky
For a Hopf algebra A, we define the structures of differential complexes on two dual exterior Hopf algebras: 1) an exterior extension of A and 2) an exterior extension of the dual…
Search for Single Top Quark Production at DZero Using Neural Networks
DZero Collaboration, V. M. Abazov et al
We present a search for electroweak production of single top quarks in ~90 pb^-1 of data collected with the DZero detector at the Fermilab Tevatron collider. Using arrays of neural…
Search for New Physics Using Quaero: A General Interface to D0 Event Data
D0 Collaboration
We describe Quaero, a method that i) enables the automatic optimization of searches for physics beyond the standard model, and ii) provides a mechanism for making high energy colli…
Approximating the satisfiability threshold for random k-XOR-formulas
Nadia Creignou, Herve Daude, Olivier Dubois
In this paper we study random linear systems with variables per equation over the finite field GF(2), or equivalently -XOR-CNF formulas. In a previous paper Creignou and Dau…
