Semileptonic B decays into higher charmed resonances.
نویسندگان
چکیده
We apply HQET to semi-leptonic B meson decays into a variety of excited charm states. Using three realistic meson models with fermionic light degrees of freedom, we examine the extent that the sum of exclusive single charmed states account for the inclusive semi-leptonic B decay rate. The consistency of form factors with the Bjorken and Voloshin sum rules is also investigated.

B Meson Transitions into Higher Mass Charmed Resonances
We use QCD sum rules to estimate the universal form factors describing the semileptonic B decays into excited charmed resonances, such as the 1 and 2 states D 1 and D ∗ 2 belonging to the s P l = 3 2 − heavy quark doublet, and the 2 and 3 states D 2 and D3 belonging to the s P l = 5 2 − doublet. “Fondazione Angelo Della Riccia” Fellow.

متن کاملCharm Physics Results from CLEO The CLEO Collaboration
We present recent results in the charm sector from the CLEO Collaboration. The data used were collected by the CLEO II and III detectors at the Cornell Electron Storage Ring (CESR). Measurements of form factors and branching fractions in semileptonic decays of D-meson and charmed-baryons, searches for CP violation and rare decays, and Dalitz analyses of D-meson decays are discussed, as well as ...
متن کاملSpectator effects in semileptonic decay of charmed baryons
It is shown that the absolute rate of the semileptonic decays of the Ξc baryons can be as much as two times higher than the semileptonic decay rate of Λc due to the Pauli interference of the strange quark. This interference effect is still larger in the semileptonic decay rate of Ωc. An experimental measurement of the difference of these rates would thus provide an important piece of informatio...
متن کاملA Bjorken sum rule for semileptonic Ωb decays to ground and excited charmed baryon states
A Bjorken sum rule for semileptonic Ω b decays to ground and excited charmed baryon states We derive a Bjorken sum rule for semileptonic Ω b decays to ground and low-lying negative-parity excited charmed baryon states, in the heavy quark limit. We discuss the restriction from this sum rule on form factors and compare it with some models.
متن کاملHQET and Exclusive B Decays
Exclusive semileptonic B decays are discussed. The emphasis is on using semileptonic decays to determine |Vub| and |Vcb|. Recent progress in our understanding of B semileptonic decays to excited charmed mesons is also reviewed. Work supported in part by the U.S. Dept. of Energy under Grant No. DE-FG03-92-ER40701.
