A note on spectator effects and quark-hadron duality in inclusive beauty decays
نویسنده
چکیده
In this paper, we evaluate the expectation values of four-quark operators for the inclusive beauty decays from the differences in the inclusive total decay rates, assuming that the heavy quark expansion converges at O(1/m). The obtained expectation values values yeilds the ratio τ(Λb)/τ(B) close to the experimental value. We further point out that the quark-hadron duality violation would be rather small allowing predictions of inclusive quantities.

Explicit quark-hadron duality in the limit of heavy quark mass is studied using the ’t Hooft model, where both partonic and hadronic amplitudes may be computed exactly. Results for weak decays of heavy mesons are presented for both standard spectator decays, where the duality limit is convincingly approached, and annihilation decays of the valence quark-antiquark pair, where the approach to asy...
متن کاملInclusive heavy hadron decays and light-cone dynamics
The governing role of light-cone dynamics in inclusive heavy hadron decay processes is demonstrated. Nonperturbative QCD effects on the processes can be systematically calculated using light-cone expansion and heavy quark effective theory. The applications of the light-cone approach to studying electroweak and strong interactions and hadron structure with semileptonic and radiative decays of be...
متن کاملSpectator Effects in Inclusive Decays of Beauty Hadrons
We present a model-independent study of spectator effects, which are responsible for the lifetime differences between beauty hadrons. These effects can be parametrized in terms of hadronic matrix elements of four four-quark operators. For B mesons, the coefficients of the non-factorizable operators turn out to be a factor 10–100 larger than those of the factorizable ones, and so the vacuum inse...
متن کاملPattern of Lifetimes of Beauty Hadrons and Quark-hadron Duality in Heavy Quark Expansion
In the heavy quark limit, the inclusive decay rate of weakly decaying heavy hadron (HQ) can be expressed in an expansion of the weak matrix elements in powers of 1/mQ, where mQ is the heavy quark mass . (In this article, though we discuss generally for a heavy system, b or c but quantitatively refer only to beauty case). At the leading order, the hadronic decay rate is given by the free heavy q...
