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…
On P-wave meson decay constants in the heavy quark limit of QCD
A. Le Yaouanc, L. Oliver, O. Pène +2
In previous work it has been shown that, either from a sum rule for the subleading Isgur-Wise function or from a combination of Uraltsev and Bjorken SR, one infers for …
Uraltsev Sum Rule in Bakamjian-Thomas Quark Models
A. Le Yaouanc, L. Oliver, O. Pène +1
We show that the sum rule recently proved by Uraltsev in the heavy quark limit of QCD holds in relativistic quark models à la Bakamjian and Thomas, that were already shown to satis…
Duality in semileptonic inclusive B-decays in potential models: regular versus singular potentials
A. Le Yaouanc, D. Melikhov, V. Morenas +3
Making use of the nonrelativistic potential model for the description of mesons, and working in the Shifman-Voloshin limit, we compare the integrated rate calculate…
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…
Large pion pole in Z_{S}^{MOM}/Z_{P}^{MOM} from Wilson action data
J. R. Cudell, A. Le Yaouanc, C. Pittori
We show that, contrarily to recent claims, data from the Wilson (unimproved) fermionic action at three different beta values demonstrate the presence of a large Goldstone boson con…
