Covariant quark model of form factors in the heavy mass limit

A. Le Yaouanc, L. Oliver, O. Pène +1

We show that quark models of current matrix-elements based on the Bakamjian-Thomas construction of relativistic states with a fixed number of particles, plus the additivity assumpt…

Uncertainties on the CP Phase $\bfalpha$ due to Penguin Diagrams

R. Aleksan, F. Buccella, A. Le Yaouanc +3

A major problem in the determination of the the CP angle $α$ , that should be measured through modes of the type $B_{d}, B ˉ_{d} \to π π, \dots,$ is the uncertainty coming from Pen…

Factorization versus Duality in Nonleptonic decays, a Quark Model Approach

A. Le Yaouanc, L. Oliver, O. Pène +1

We study in a quark model the contradiction between factorization and duality found in nonleptonic decays at next to leading order in $1/ N_{c}$ , concentrating on quark exchange mecha…
