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…
Quark pseudoscalar vertex and quark mass function with clover fermions : spontaneous symmetry breaking, OPE, symmetry restoration at small volume
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We study the quark mass function on hypercubic lattices, in a large range of physical volumes and cutoffs. To avoid the very large Wilson term artefact, we exploit the relation bet…
Non-perturbative Power Corrections to Ghost and Gluon Propagators
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +5
We study the dominant non-perturbative power corrections to the ghost and gluon propagators in Landau gauge pure Yang-Mills theory using OPE and lattice simulations. The leading or…
Suppressed decay into open charm for the Y(4260) being an hybrid
E. Kou, O. Pene
We investigate the Y(4260) resonance recently discovered by the Babar collaboration. We propose the observation of its decay into J/psi pi pi and its non observation into open char…
Remarks on sum rules in the heavy quark limit of QCD
A. Le Yaouanc, L. Oliver, O. Pene +2
We underline a problem existing in the heavy quark limit of QCD concerning the rates of semileptonic B decays into P-wave mesons, where (wide states) or…
Asymptotic behavior of the ghost propagator in SU3 lattice gauge theory
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +5
We study the asymptotic behavior of the ghost propagator in the quenched SU(3) lattice gauge theory with Wilson action. The study is performed on lattices with a physical volume fi…
