The strong coupling constant at small momentum as an instanton detector
Ph. Boucaud, F. De Soto, A. Le Yaouanc +5
We present a study of at small p computed from the lattice. It shows a dramatic law which can be understood within an instanton liquid model. In this fra…
Possible explanation of the discrepancy of the light-cone QCD sum rule calculation of g(D*Dpi) coupling with experiment
D. Becirevic, J. Charles, A. LeYaouanc +3
The introduction of an explicit negative radial excitation contribution in the hadronic side of the light cone QCD sum rule (LCSR) of Belyaev, Braun, Khodjamirian and Ruckl, can ex…
Experimental Results on Heavy Quarks
A. Stocchi
This paper reviews the results presented at the 31st ICHEP on Heavy Quarks, with emphasis on those related to the determinationof the unitarity triangle parameters.
Universality of nonperturbative QCD effects in radiative B-decays
S. Descotes-Genon, C. T. Sachrajda
We demonstrate, by an explicit one-loop calculation, that at leading twist the nonperturbative effects in B -> gamma l nu, B -> gamma gamma and B -> gamma l+ l- radiative decays ar…
SuSpect: a Fortran Code for the Supersymmetric and Higgs Particle Spectrum in the MSSM
Abdelhak Djouadi, Jean-Loic Kneur, Gilbert Moultaka
We present the Fortran code SuSpect version 2.3, which calculates the Supersymmetric and Higgs particle spectrum in the Minimal Supersymmetric Standard Model (MSSM). The calculatio…
Can radiative magnification of mixing angles occur for two-zero neutrino mass matrix textures?
Gautam Bhattacharyya, Amitava Raychaudhuri, Arunansu Sil
Neutrino Majorana masses and mixings can be generated from a dimension-5 operator within the standard model particle content. After a review of the mechanism of radiative enhanceme…
O.P.E. and Power Corrections to the QCD coupling constant
Ph. Boucaud, F. De Soto, A. Donini +6
Lattice data seems to show that power corrections should be convoked to describe appropriately the transition of the QCD coupling constant running from U.V. to I.R. domains. Those…
Sum rules in the heavy quark limit of QCD
A. Le Yaouanc, L. Oliver, J. -C. Raynal
In the leading order of the heavy quark expansion, we propose a method within the OPE and the trace formalism, that allows to obtain, in a systematic way, Bjorken-like sum rules fo…
Kinetic equilibration in heavy ion collisions: the role of elastic processes
Julien Serreau
We discuss the question of thermalization during the very early stages of a high energy heavy ion collision. We review a recent study where we explicitely showed that, contrarily t…
An Instanton Picture O.P.E. <A^2> Condensate?
Ph. Boucaud, F. De Soto, A. Donini +6
Gluon two- and three-point Green Functions computed in Landau gauge from the lattice show the existence of power corrections to the purely perturbative expressions, that can be exp…
Dilepton production from the Color Glass Condensate
F. Gelis, Jamal Jalilian-Marian
We consider dilepton production in high energy proton-nucleus (and very forward nucleus-nucleus) collisions. Treating the target nucleus as a Color Glass Condensate and describing…
Variational analysis of the deconfinement phase transition
I. I. Kogan, A. Kovner, J. G. Milhano
We study the deconfining phase transition in 3+1 dimensional pure SU(N) Yang-Mills theory using a gauge invariant variational calculation. We generalize the variational ansatz of P…
Confronting Spectral Functions from e+e- Annihilation and tau Decays: Consequences for the Muon Magnetic Moment
M. Davier, S. Eidelman, A. Hocker +1
Vacuum polarization integrals involve the vector spectral functions which can be experimentally determined from two sources: (i) e+e- annihilation cross sections and (ii) hadronic…
A general analysis with trilinear and bilinear R-parity violating couplings in the light of recent SNO data
Asmaa Abada, Gautam Bhattacharyya, Marta Losada
We analyse an extension of the minimal supersymmetric standard model including the dominant trilinear and bilinear R-parity violating contributions. We take the trilinear terms fro…
A transparent expression of the A^2-Condensate's renormalisation
Ph. Boucaud, F. De Soto, A. Le Yaouanc +5
We give a more transparent understanding of the vacuum expectation value of the renormalised local operator A^2 by relating it to the gluon propagator integrated over the momentum.…
First lattice QCD estimate of the g_{D^* D pi} coupling
A. Abada, D. Becirevic, Ph. Boucaud +5
We present the results of the first lattice QCD study of the strong coupling g_{D^* D pi}. From our simulations in the quenched approximation, we obtain g_{D^* D pi} = 18.8 +/- 2.3…
The CKM Matrix and The Unitarity Triangle: Another Look
Andrzej J. Buras, Fabrizio Parodi, Achille Stocchi
The unitarity triangle can be determined by means of two measurements of its sides or angles. Assuming the same relative errors on the angles and the sides , w…
The fundamental constants and their variation: observational status and theoretical motivations
Jean-Philippe Uzan
This article describes the various experimental bounds on the variation of the fundamental constants of nature. After a discussion on the role of fundamental constants, of their de…
Electromagnetic corrections in the anomaly sector
B. Ananthanarayan, B. Moussallam
Chiral perturbation theory in the anomaly sector for is extended to include dynamical photons, thereby allowing a complete treatment of isospin breaking. A minimal set of i…
Photon production in high energy proton-nucleus collisions
Francois Gelis, Jamal Jalilian-Marian
We calculate the photon production cross-section in collisions under the assumption that the nucleus has reached the saturation regime, while the proton can be described by th…
Does parton saturation at high density explain hadron multiplicities at RHIC ?
R. Baier, A. H. Mueller, D. Schiff +1
We discuss the recent claim that hadron multiplicities measured at RHIC energies are directly described in terms of gluon degrees of freedom fixed from the initial conditions of ce…

P. Aurenche, F. Gelis, H. Zaraket
In this paper, we derive a simple sum rule satisfied by the gluon spectral function at finite temperature. This sum rule is useful in order to calculate exactly some integrals that…
