Semileptonic Decays of Heavy Mesons: a Status Report *
نویسندگان
چکیده
We present intermediate results on our ongoing investigation concerning semileptonic decays of heavy pseu-doscalar mesons into pseudoscalar and vector mesons. The corresponding formfactors are evaluated at several momenta and appropriate combinations of four light and four heavy quarks, which are chosen to allow for an extrapolation into the B Meson region. In order to obtain clear groundstate signals we apply gauge invariant " Wuppertal " smearing to the quarks. The analysis is based on 32 quenched gauge configurations of size 24 3 × 64 at β = 6.3, with Wilson fermions.

Non - factorizable terms , heavy quark masses , and semileptonic decays of D and B mesons
Non-factorizable terms, heavy quark masses, and semileptonic decays of D and B mesons. Abstract The non-factorizable terms in the operator product expansion have been recognized as one of theoretical obstacles for precision determination of the mixing parameter V ub from semileptonic B decays. It is pointed out here that the recent CLEO data on the parameters of the heavy quark expansion λ 1 an...

We report on exploratory studies of heavy-light meson semileptonic decays using AsqTad light quarks, NRQCD heavy quarks and Symanzik improved glue on coarse quenched lattices. Oscillatory contributions to three-point correlators coming from the staggered light quarks are found to be handled well by Bayesian fitting methods. B meson decays to both the Goldstone pion and to one of the point-split...

Using quasipotential approach, we have studied exclusive semileptonic decays of heavy mesons with the account of relativistic effects. Due to more complete relativistic description of the s quark more precise expressions for semileptonic form factors are obtained. Various differential distributions in exclusive semileptonic decays of heavy mesons are calculated. It is argued that consistent acc...
متن کاملSemileptonic decays of heavy-light pseudoscalar mesons
I discuss the results of a recent quenched lattice calculation of the two independent form factors parametrizing the semileptonic decays between heavy-light pseudoscalar mesons. The differential decay rate of the process B → Dℓν has been calculated at non vanishing momentum transfer both in the case of the light leptons ℓ = e, µ and in the case of a non vanishing lepton mass ℓ = τ.

New (preliminary) results for the form factors relevant for the semileptonic decays of heavy pseudoscalar to a light vector meson are presented. In particular, we discuss the form factors for D → K * and B → ρ modes.
