Isotopic splittings and OPE in B → D semileptonic decays
It is shown that the kinematical difference in the decays B − → D 0 ℓ ˜ ν and B 0 → D + ℓ ˜ ν due to the isotopic mass splittings of the B and D mesons is compensated in the total decay rate by an appropriate difference in the lepton spectra. Thus there is no effect on the total decay rates in the linear order in the isotopic mass splittings, as required by the general consideration based on th...
متن کاملDoubly Heavy Systems: Decays and Ope
We discuss questions related to the application of OPE for the long-lived systems with two heavy flavors. The values of quark masses entering such calulations are constrained by use of currently available data on the lifetimes of B d and B c-mesons. The lifetimes of doubly charmed baryons at these values of parameters are evaluated. The necessary comments on the difference in the results obtain...
متن کاملHadronic Bu and Bd decays
The PEP-II and KEKB B factories have very recently produced a number of new measurements or limits for B decay modes to hadronic final states. These include some b → c modes bearing on the interpretation of experiments aiming to measure the CKM angle γ (φ3), charmless baryonic three-body final states with their two-body substructure, and a number of charmless mesonic branching fractions and cha...
متن کاملSemileptonic Decays at Sld
The lifetimes of B + and B 0 mesons have been measured using a sample of 150,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between 1993 and 1995. The analysis identiies the semileptonic decays of B mesons with high p; p t leptons and reconstructs the B meson decay length and charge by v ertexing the lepton with a partially reconstructed D meson. This method results in a sam...

The analysis identies the semileptonic decays of B mesons with high (p; p t) leptons and reconstructs the B meson decay length and charge by v ertexing the lepton with a partially reconstructed D meson.
