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…
Soft dynamics in heavy-light mesons
Damir Bećirević, Emmanuel Chang, Alain Le Yaouanc
We compute the radial distributions of the scalar, vector and axial charge density in the heavy-light mesons. We present the results obtained for both the lowest lying static heavy…
A Ghost Story II: Ghosts, Gluons and the Gluon condensate beyond the IR of QCD
J. Rodríguez-Quintero, Ph. Boucaud, F. De Soto +4
Beyond the deep IR, the analysis of ghost and gluon propagators still keeps very interesting non-perturbative information. The Taylor-scheme coupling can be computed and applied to…
A Ghost Story: Ghosts and Gluons in the IR regime of QCD
O. Pène, Ph. Boucaud, J. P. Leroy +3
We discuss the different methods to obtain reliable informations about the deep infra-red behaviour of the gluon and ghost Green functions in QCD. We argue that a clever combinatio…
Gribov's horizon and the ghost dressing function
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We study a relation recently derived by K. Kondo at zero momentum between the Zwanziger's horizon function, the ghost dressing function and Kugo's functions and . We agree w…
On internal structure of the heavy-light mesons
Damir Becirevic, Emmanuel Chang, Alain Le Yaouanc
We compute the radial distributions of the vector and axial charge density as well as of the matter density in the heavy-light mesons on the lattice. The results for the lowest lyi…
