Analysis of the semileptonic B c → B ∗ u l + l − decay from QCD sum rules
نویسنده
چکیده
We analyze the semileptonic Bc → B∗ ull decay in the frame work of the Standard Model. We calculate the Bc to B ∗ u transition form factors in QCD sum rules. Analytical expressions for the spectral densities and gluon condensates are presented. The branching ratio of the Bc → B∗ ull decay is calculated, and it is obtained that this decay can be detectable at forthcoming LHC machines.

We set up sum rules for heavy lambda decays in a full QCD calculation which in the heavy quark mass limit incorporates the symmetries of heavy quark effective theory. For the semileptonic decay of the Λ b we find at the zero recoil point a violation of the heavy quark symmetry of more than 20%. We test the method by calculating the decay width of the semileptonic Λ c decay and obtain a reasonab...
متن کاملAnd Qcd Sum Rules in Hqet ⋆
I review recent developments in Heavy Quark Effective Theory (HQET) that lead to an almost model–independent determination of the |Vcb| element of the Cabibbo– Kobayashi–Maskawa matrix from exclusive semileptonic B → D(∗) decays. In particular, I compare the theoretical uncertainties in the B → Dl ν̄ and the B → D l ν̄ decay modes. I discuss the applications of QCD sum rules within HQET to semile...
متن کامل0(1430)ll decay within QCD sum rules
Form factors of rare B → K 0 (1430)l+l− decay are calculated within three–point QCD sum rules, with K 0 (1430) being the p–wave scalar meson. The branching ratios are estimated when only short, as well as short and long distance effects, are taken into account. It is obtained that the B → K 0 (1430)l+l− (l = e, μ) decay is measurable at LHC. Measurement of these branching ratios for the semilep...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
متن کاملQCD sum rule analysis of the decays B-->Kl+l- and B-->K*l+l-
We use QCD sum rules to calculate the hadronic matrix elements governing the rare decays B → Kl+l− and B → K∗l+l− induced by the flavour changing neutral current b → s transition. We also study relations among semileptonic and rare B → K(∗) decay form factors. The analysis of the invariant mass distribution of the lepton pair in B → K(∗)l+l− and of the angular asymmetry in B → K∗l+l− provides u...
