Sum rules in the heavy quark limit of QCD and Isgur-Wise functions
F. Jugeau, A. Le Yaouanc, L. Oliver +1
Using the OPE, we formulate new sum rules in the heavy quark limit of QCD. These sum rules imply that the elastic Isgur-Wise function is an alternate series in powers of $(w…
Are the low-momentum gluon correlations semiclassically determined?
Ph. Boucaud, F. De Soto, A. Le Yaouanc +1
We argue that low-energy gluodynamics can be explained in terms of semi-classical Yang-Mills solutions by demonstrating that lattice gluon correlation functions fit to instanton li…
Analytical methods in heavy quark physics and the case of
A. Le Yaouanc
Analytical methods in heavy quark physics are shortly reviewed, with emphasis on the problems of dynamical calculations. Then, attention is attracted to the various difficulties ra…
Subleading form factors at order 1/m_Q in terms of leading quantities using the non-forward amplitude in HQET
F. Jugeau, A. Le Yaouanc, L. Oliver +1
We consider the non-forward amplitude within the Heavy Quark Effective theory. We show that one can obtain new information on the subleading corrections in 1/m_Q. We illustrate the…
Lattice measurement of the Isgur-Wise functions tau_1/2 and tau_3/2
D. Becirevic, B. Blossier, Ph. Boucaud +5
We propose a method to compute the Isgur-Wise form factors tau_1/2(1) and tau_3/2(1) for the decay of B mesons into orbitally excited (P wave) D** charmed mesons on the lattice in…
