Qcd Calculation of Heavy Meson Semileptonic Transitions
نویسندگان
چکیده
I review the QCD sum rules calculations of the form factors governing the semileptonic decays of charmed and beauty mesons. In particular, I discuss the predicted dependence of the various form factors on q and how it can be obtained for the form factors of vector and axial currents. In some cases the q dependence, computed by QCD sum rules, is different from the outcome of lattice QCD. A Tau-Charm factory could be an efficient tool to study this aspect of the charmed meson transitions. Talk delivered at the Third Workshop on a Tau-Charm Factory, Marbella (Spain) 1-6 june 1993.

Semileptonic and Rare B-Meson Transitions in a QCD Relativistic Potential Model
Using a QCD relativistic potential model, previously applied to the calculation of the heavy meson leptonic constants, we evaluate the form factors governing the exclusive decays B → ρ`ν, B → Kγ and B → K``. In our approach the heavy meson is described as a Qq bound state, whose wave function is solution of the relativistic Salpeter equation, with an instantaneous potential displaying Coulombic...
متن کاملThe semileptonic decays of the B c meson
We study the semileptonic transitions Bc → ηc, J/ψ, D, D∗, B, B∗, Bs, B∗ s in the framework of a relativistic constituent quark model. We use experimental data on leptonic J/ψ decay, lattice and QCD sum rule results on leptonic Bc decay, and on radiative ηc transitions to adjust the quark model parameters. We compute all form factors of the above semileptonic Bc-transitions and give predictions...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
متن کاملHeavy-Meson Observables via Dyson-Schwinger Equations
We summarise a Dyson-Schwinger-equation-based calculation of an extensive range of lightand heavy-meson observables, characterised by heavy-meson leptonic decays, semileptonic heavy-to-heavy and heavy-to-light transitions B → D, D, ρ, π; D → K, K, π, radiative and strong decays B (s) → B(s)γ; D (s) → D(s)γ, Dπ, and the rare B → Kγ flavour-changing neutral-current process. In the calculation the...
متن کاملRadiative heavy meson transitions
We evaluate the radiative and hadronic decay rates of the D mesons using the Heavy Quark Effective Theory and the Vector Meson Dominance hypothesis. We also estimate the width of the B electromagnetic transitions and the radiative decays of positive parity J = 0, 1 charmed mesons. e-mail address: [email protected] In this letter we wish to show that the heavy quark and chiral SU(3)L × SU(3...
