چکیده
We compute the branching ratio of inclusive B → ηXs decay based upon the QCD anomaly mechanism: b → s + g → s + g + η. To obtain a reliable B → ηXs branching ratio, we calculate the b → s+ g form factors up to the next-to-leadinglogarithmic(NLL) approximation. We point out that the Standard Model prediction for B → ηXs is consistent with the CLEO data, in contrast to the claims of some previous works.

The experimental hint of large B → η ′ + X s could be linked to the b → s penguins via the gluon anomaly. If running α s is used in the η ′-g-g coupling, the standard b → sg * penguin alone may not be enough, calling for the need of dipole b → sg from new physics. The latter could be at 10% level as suggested by charm counting and B s.l. problems. The added new physics contribution not only bri...

We report results on fB and semi-leptonic B decay form factors using NRQCD. We investigate 1/M scaling behavior of decay amplitudes. For fB Effect of higher order relativistic correction terms are also studied.

We give an estimate of the C-even B 0 ¯ B 0 background coming from the radia-tive decay Υ(4S) → B 0 ¯ B 0 γ at B-factories. Our result B(Υ(4S) → B 0 ¯ B 0 γ) ≃ 3× 10 −9 shows that such background could be safely neglected in the analyses of CP violating effects.

We present a quenched calculation of the form factors of the semileptonic weak decay B → πl¯ ν with O(1/mQ) NRQCD heavy quark and Wilson light quark on a 16 3 × 32 lattice at β = 5.8. The form factors are evaluated at six heavy quark masses, in the range of mQ ∼ 1.5 − 8 GeV. 1/mQ dependence of matrix elements are investigated and compared with HQET predictions. We observe clear signal for the f...
