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…
MIXING AND CP VIOLATION IN D MESONS
A. Le Yaouanc, L. Oliver, O. Pène +1
We review mixing and CP violation in mesons, emphasizing the differences with the other pseudoscalar mesons in the Standard Model, and show that mesons can be useful to loo…
WEAK TRANSITIONS OF HEAVY MESONS AND THE QUARK MODEL
A. Le Yaouanc, L. Oliver, O. Pène +1
We underline the general features of the constituent quark model and its success in the description of the spectrum and transitions of hadrons made up of light or heavy quarks, bri…
The Polarization Puzzle
R. Aleksan, A. Le Yaouanc, L. Oliver +2
We point out that current estimates of form factors fail to explain the non-leptonic decays and that the combination of data on the semi-leptonic decays $D \to…
B To Light Meson Form Factors
R. Aleksan, A. Le Yaouanc, L. Oliver +2
The heavy to light form factors in decays are discussed. Critical discussion of theoretical approaches is made with special emphasis on their failure to describe the $B \to K^{…
