Heavy baryon wave functions, Bakamjian-Thomas approach to form factors, and observables in transitions
D. Bečirević, A. Le Yaouanc, V. Morénas +1
Motivated by the calculation of observables in the decays , as tests of Lepton Flavor Universality, we present a calculati…
Simple operator formulation of the Bakamjian-Thomas approach to heavy quark current , with generalisation to HQET, and with applications to transitions of Lambda-b
Damir Becirevic, Vincent Morenas, Alain Le-Yaouanc +1
Starting from the general formulation of current matrix elements in the Bakamjian-Thomas (BT) approach to quark models, certain aspects of their heavy quark limit are exhibited in…
Three-gluon running coupling from lattice QCD at : a consistency check of the OPE approach
Ph. Boucaud, M. Brinet, F. De Soto +4
We present a lattice calculation of the renormalized running coupling constant in symmetric (MOM) and asymmetric () momentum substraction schemes including …
High statistics determination of the strong coupling constant in Taylor scheme and its OPE Wilson coefficient from lattice QCD with a dynamical charm
B. Blossier, Ph. Boucaud, M. Brinet +5
This paper reports on the determination of from lattice simulations with 2+1+1 twisted-mass dynamical flavours {\it via} the computation of the ghost-gluon coupling renormali…
Testing the OPE Wilson coefficient for from lattice QCD with a dynamical charm
B. Blossier, Ph. Boucaud, M. Brinet +5
Gluon and ghost propagators data, obtained in Landau gauge from lattice simulations with two light and two heavy dynamical quark flavours (=2+1+1), are described here with a r…
The strong running coupling at and mass scales from lattice QCD
B. Blossier, Ph. Boucaud, M. Brinet +6
This letter reports on the first computation, from data obtained in lattice QCD with and quarks in the sea, of the running strong coupling via the ghost-gluon coupling…
