Non-Spectator Contributions to Inclusive Charmless B Decays
نویسندگان
چکیده
The light quarks inside B mesons are usually treated as spectators and do not affect the decay rates which are assumed to be purely due to b quark decays. In this paper we calculate the non-spectator contributions to inclusive charmless B decays due to the spectator effects. We find that the non-spectator contributions to the branching ratio for B̄ are small (< 2 × 10), but the contributions to ∆S = 0 and ∆S = −1, B decay branching ratios can be as large as −7.5× 10 and 2× 10, respectively. These contributions may play an important role in rare charmless B decays. Typeset using REVTEX

We study the inclusive charmless semileptonic decay of Λb, Λb → Xulνl, in the framework of heavy quark expansion and find that the rate is substantially enhanced by spectator effect. We obtain Br(b → Xulνl) to be 1.13× 10 −3 for |Vub| = 3.3× 10 . We discuss our result in light of the recent LEP measurements of the charmless semileptonic branching ratio where such enhancement was not taken into ...
متن کاملINCLUSIVE SEMILEPTONIC DECAYS OF BOTTOM BARYONS AND MESONS INTO CHARMED AND UNCHARMED FINAL STATES: THE CASE OF INFINITELY HEAVY b AND c QUARKS*
Spectator model decay rates are predicted for inclusive semileptonic decays of the A* baryon and the B meson, in the limit of a very heavy b quark, in lowest order of perturbative QCD. For charmless final states the result is only achieved in a short distance limit, sharing similarities with the deep inelastic scattering situation, and allowing for a parton model interpretation. In all cases th...
متن کاملReexamining charmless B → PV decays in QCD factorization approach
Using the QCD factorization approach, we reexamine the two-body hadronic charmless B-meson decays to final states involving a pseudoscalar (P ) and a vector (V ) meson, with inclusion of the important penguin contractions of the spectator-scattering amplitudes induced by the b → Dg∗g∗ (with D = d or s, and g∗ denoting an off-shell gluon) transition, which are of order αs. Their impacts on the C...
متن کاملK(k)x: Decay Distributions, Branching Ratios and Cp Asymmetries
The semi-inclusive charmless hadronic decays B → K(K)X , where X is a hadronic recoil system containing no charmed and strange particles, are useful for studying direct CP violation and determining the weak phase γ . Direct CP violation can also be studied with exclusive or inclusive charmless hadronic B decays. Although theoretical uncertainties in inclusive decays may be small, it is experime...
متن کاملStatus of Ψ ′ ′ Decays to Charmless Final States
The non-DD̄ decays of the ψ′′ = ψ(3770) resonance are discussed and possibilities for further measurements are noted. These decays can shed light on S–D mixing, the “missing” ψ′ = ψ(3686) decays, a possible discrepancy between the total and DD̄ cross sections at the ψ′′, and rescattering effects contributing to enhanced b → s penguin amplitudes in B meson decays. The importance is stressed of mea...
