Pseudoscalar Vertex and Quark Masses
J-R. Cudell, A. Le Yaouanc, C. Pittori
We analyse available data on the quark pseudoscalar vertex and extract the contribution og the Goldstone boson pole. The strength of the pole is found to be quite large at presentl…
Inclusive decay of B mesons into or
R. Aleksan, M. Zito, A. Le Yaouanc +3
We compute the inclusive decay rates including lowest order QCD corrections on the quark legs, and compare with existing data. Unlike the short distance Q…
Measuring with B transitions
R. Aleksan, M. Zito, A. Le Yaouanc +3
We propose the determination of the CKM matrix element by the measurement of the spectrum of , dominated by the spectator quark model mechanism $\bar{b}…
Heavy-to-Light Form Factors in the Final Hadron Large Energy Limit of QCD
J. Charles, A. Le Yaouanc, L. Oliver +2
We argue that the Large Energy Effective Theory (LEET), originally proposed by Dugan and Grinstein, is applicable to exclusive semileptonic, radiative and rare heavy-to-light trans…
Heavy-to-Light Form Factors in the Final Hadron Large Energy Limit: Covariant Quark Model Approach
J. Charles, A. Le Yaouanc, L. Oliver +2
We prove the full covariance of the heavy-to-light weak current matrix elements based on the Bakamjian-Thomas construction of relativistic quark models, in the heavy mass limit for…
g-coupling (g_B*Bpi,g_D*Dpi); A quark model with Dirac equation
Damir Becirevic, Alain Le Yaouanc
We discuss the strong coupling of heavy mesons to a pion g, in the heavy quark limit. This quantity is quite remarkable since its values as estimated by different methods (various…
