Isospin corrections to charmless semileptonic B-->V transitions.
We compute isospin corrections to the charmless semileptonic B → V transitions arising from ρ− ω mixing and discuss its relevance in the determination of Vub. PACS numbers: 13.20.He, 12.15.Hh, 12.40.Vv. 11.30.Hv The first measurement of an exclusive charmless semileptonic B decay has been reported recently by the CLEO Collaboration [1,4]. The yields for B → πlνl reported in Refs. [1,4] turn out...
متن کاملSemileptonic B Decays Recent Results from Lep and Comparison with Υ(4s) Data
Recent analyses of the LEP and Υ(4S) data have better outlined the picture of semileptonic B decays. Results on inclusive and exclusive decay branching fractions and on the extraction of the |V ub | and |V cb | elements of the CKM mixing matrix are discussed, together with some of the still open questions and the sources of model systematics.
متن کاملEuropean Organization for Nuclear Research Measurement of the Inclusive Charmless Semileptonic Branching Fraction of Beauty Hadrons and a Determination of Jv Ub J at Lep
A measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons, b ! X u ``, has been performed using almost two million hadronic Z decays collected by the L3 experiment at LEP, yielding the result:
متن کاملConstraints on Semileptonic Form - Factors Fromdispersive Sum Rules
I briefly discuss the derivation of dispersive sum rules constraining semileptonic form-factors. I outline the use of these constraints in the context of charmless semileptonic decays and suggest how, in combination with other theoretical and experimental information, they may reduce the uncertainties in the extraction of V ub .
متن کاملFurther remarks on the isospin breaking in charmless semileptonic B decays
We consider the isospin breaking corrections to charmless semileptonic decays of B mesons. Both, the recently measured branching ratios of exclusive decays by the CLEO Collaboration and the end-point region of the inclusive lepton spectrum in form factor models, can be affected by these corrections. Isospin corrections can affect the determination of |Vub| from exclusive semileptonic B decays a...
