The Pion Light-Cone Wave Function Phi_pi on the lattice: a partonic signal?
A. Abada, Ph. Boucaud, G. Herdoiza +4
We determine the conditions required to study the pion light-cone wave function Phi_pi with a new method: a direct display of the partons constituting the pion. We present the prel…
Power Corrections to Perturbative QCD and OPE in Gluon Green Functions
D. Becirevic, Ph. Boucaud, F. De Soto +6
We show that QCD Green functions in Landau Gauge exhibit sizable corrections to the expected perturbative behavior at energies as high as 10 GeV. We argue that these are…
Unquenched calculation of alpha_s from Green functions: progress report
Ph. Boucaud, J. P. Leroy, J. Micheli +4
We present preliminary results on the computation of the QCD running coupling constant in the MOM_tilde scheme and Landau gauge with two flavours of dynamical Wilson quarks. Gluon…
Preliminaries on a Lattice Analysis of The Pion Light-cone Wave function: a Partonic Signal?
A. Abada, Ph. Boucaud, G. Herdoiza +4
We present the first attempt of a new method to compute the pion light-cone wave function (LCWF) on the lattice. We compute the matrix element between the pion and the vacuum of a…
Testing Landau gauge OPE on the Lattice with a Condensate
Ph. Boucaud, A. Le Yaouanc, J. P. Leroy +3
Using the operator product expansion we show that the correction to the perturbative expressions for the gluon propagator and the strong coupling constant resulting from…
