Is there a non-standard-model contribution in non-leptonic b to s decays?
arXiv:0910.1521
Abstract
The data on high-precision flavour observables reveal certain puzzles when compared to Standard Model expectations based on a global fit of the CKM unitarity triangle and general theoretical estimates. The discussion of these tensions in the channels B to J/psi K, B to phi K, and B to pi K, and the deduced constraints for New Physics operators of the class (bs)(qq) form the content of this talk.
