Dissipative Effects in Semileptonic B-b Decays
نویسنده
چکیده
We study the time evolution and decay of the neutral B-meson system using quantum dynamical semigroups. New, nonstandard terms appear in the expression of relevant observables; they can be parametrized in terms of six phenomenological constants. Although very small, these parameters may be detected in the new generation of dedicated B-meson experiments.

The study of the semileptonic B-meson decays is the most accessible and cleanest way to determine the CKM matrix elements |Vcb| and Vub. These decays also provide experimental access to study the QCD form-factors, heavy quark masses, and HQE parameters. The theoretical description of semileptonic B-meson decays at the parton level is very simple because there is no interaction between leptonic ...
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...

In this section, we discuss some of the key questions related to semileptonic decays of B mesons: the inclusive semileptonic branching fraction, the determination of jV cb j and jV ub j from inclusive and exclusive measurements, recent progress in exclusive semileptonic decays, and form factor measurements and tests of heavy-quark eeective theory. We emphasize the uncertainties that arise in ex...
متن کاملCharged Higgs Effects on Exclusive Semi-tauonic B Decays
We study effects of charged Higgs boson exchange in the B semileptonic decays B̄ → D(∗)τ ν̄τ . Both branching ratio and τ polarization are examined. We use the recent experimental data on semileptonic B decays and the heavy quark effective theory in order to reduce theoretical uncertainty in the hadronic form factors. Theoretical uncertainty in the branching ratio is found to be rather small and ...
