Chiral Dynamics and S-wave Contributions in Semileptonic B decays

The flavor-changing neutral current process b → sll is beneficial to testing the standard model and hunting for new physics scenarios. In exclusive decay modes like B → K(892)ll, the S-wave effects may not be negligible and thus have to be reliably estimated. Using the scalar form factors derived from dispersion relations in two channels and matched to Chiral Perturbation Theory, we investigate...

S Mixing Using Inclusive and Semileptonic B Decays at Sld

We set a preliminary 95% C.L. exclusion on the oscillation frequency of B 0 s B 0 s mixing using a sample of 250,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between January 1996 and March 1998. The analyses determine the b-hadron avor at production by exploiting the large forward-backward asymmetry of polarized Z 0 ! bb decays as well as information from the hemisphere op...

Experimental Status of b → s ( d ) γ Decays

Radiative penguin decays provide an indirect probe for physics beyond the Standard Model and contribute to the determination of the CKM matrix elements. Copious quantities of B mesons produced at the B–Factories permit precision measurements of radiative penguin decays. We review the experimental status of the radiative penguin processes b → s(d)γ.
