6 Analysis of exclusive B s → D s 0 ( 2317 ) l ν̄ l decay in “ full ” QCD

چکیده
The transition form factors of the semileptonic decay Bs into scalar Ds0(2317) meson is calculated in the framework of 3–point QCD sum rule. The branching ratio is found to be ∼ 10−3 for the Bs → Ds0(2317)lν̄l (l = e, μ) decay, and ∼ 10−4 for the Bs → Ds0(2317)τ ν̄τ decay, respectively. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

And 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...

The inclusive B → Xs ν ν̄ decay rate, on which no experimental bound exists to date, can be constrained by searching for large missing energy events in B decays. Carefully examining the experimental and theoretical aspects of such an analysis, we argue that the published ALEPH limit on BR(B → τ ν̄) implies, conservatively, the bound BR(B → Xs ν ν̄) < 3.9×10−4, which is less than one order of magni...
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 کاملUncertainties in the Determination of |Vcb|
I discuss the theoretical uncertainties in the extraction of |Vcb| from semileptonic decays of B mesons, taking into account the most recent theoretical developments. The main sources of uncertainty are identified both for the exclusive decay mode B → D∗l ν̄ and for the inclusive channel B → X l ν̄. From an analysis of the available experimental data, I obtain |Vcb|excl = 0.041 ± 0.003exp ± 0.002...

Using the soft-pion theorem and the assumption of the dominance of the Ds(0 )DK coupling we include the contribution of DK continuum into the QCD Sum Rule for DsJ (2317). We find that this contribution can significantly lower the mass and decay constant of Ds(0 ) state. For the value of the pole mass Mc = 1.38 GeV we obtain the mass of D + s (0 ) M0 = 2.31± 0.03 GeV in the interval s0 = 7.0 − 8...
