Memorino on the `1/2 vs. 3/2 Puzzle' in
I. I. Bigi, B. Blossier, A. Le Yaouanc +5
After the successes the OPE description has scored in describing decays, we need to study what can be said about the composition of the hadronic final stat…
Sum rules for leading and subleading form factors in Heavy Quark Effective Theory using the non-forward amplitude
F. Jugeau, A. Le Yaouanc, L. Oliver +1
Within the OPE, we the new sum rules in Heavy Quark Effective Theory in the heavy quark limit and at order 1/m_Q, using the non-forward amplitude. In particular, we obtain new sum…
Lagrangian perturbations at order 1/m and the non-forward amplitude in Heavy Quark Effective Theory
F. Jugeau, A. Le Yaouanc, L. Oliver +1
We pursue the program of the study of the non-forward amplitude in HQET. We obtain new sum rules involving the elastic subleading form factors at order $1/m…
The tensor force in Heavy Quark Effective Theory
F. Jugeau, A. Le Yaouanc, L. Oliver +1
We extend the formalism of Leibovich, Ligeti, Stewart and Wise in the 1/m_Q expansion of Heavy Quark Effective Theory for the B semileptonic decays into excited D[(3/2)^+] mesons t…
Suppressed decay into open charm for the Y(4260) being an hybrid
E. Kou, O. Pene
We investigate the Y(4260) resonance recently discovered by the Babar collaboration. We propose the observation of its decay into J/psi pi pi and its non observation into open char…
The decays and the Isgur-Wise functions ,
F. Jugeau, A. Le Yaouanc, L. Oliver +1
We perform a phenomenological analysis of the decays , where is a -wave excited meson with total angular momentum or for…
