Colour-straight Four-quark Operators and Lifetimes of Beautiful Hadrons
نویسنده
چکیده
Using the relation between the harmonic oscillator wave function and the light quark scattering form factor, the expectation values of colour-straight fourquark operators are evaluated and found to be directly proportional to the cubic power of the oscillator strength. It is predicted that the ratio τ(Λb)/τ(B) ≈ 0.82 against the experimental 0.79 ± 0.06. PACS numbers: 12.39.Hg, 13.20.He, 14.20.Mr, 14.20Nd Submitted to Physical Review D Typeset using REVTEX 1

Four-fermion Heavy Quark Operators and Light Current Amplitudes in Heavy Flavor Hadrons
We introduce and study the properties of the “color-straight” four-quark operators containing heavy and light quark fields. They are of the form (b̄Γbb)(q̄Γqq) where both brackets are color singlets. Their expectation values include the bulk of the nonfactorizable contributions to the nonleptonic decay widths of heavy hadrons. The expectation values of the color-straight operators in the heavy ha...

5 Quark-hadron duality 51 6 Conclusion 55 ii 0.1 Preface This Thesis is a review of the inclusive decays of heavy hadron. It is based on the author's study of two issues which are important in the description of the inclusive beauty decays given by the heavy quark expansion. • Evaluation of the expectation values of the four-quark operators in the heavy quark expansion, • Study on the validity ...
متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
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 کاملLifetimes of Charmed Hadrons Revisited. Facts and Fancy
The problem of the hierarchy of lifetimes of charmed hadrons is reviewed. The QCD-based theory of preasymptotic eeects in inclusive weak decays dating back to the beginning of the eighties is now entering its mature phase. Combining recent and old results we argue that the observed hierarchy reeects most intimate features of the hadronic structure. The problem of a wide spread of lifetimes of c...
