Contribution

It provides the first observation of Lambda_b -> Lambda mu+ mu- and updates measurements of angular observables in B -> K* mu+ mu- decays.

Findings

First observation of Lambda_b -> Lambda mu+ mu- decay.

Updated angular analysis results for B -> K* mu+ mu-.

Consistent results with Standard Model predictions.

Abstract

We summarize recent b -> s mu mu results from the CDF experiment based on the full 9.6 fb-1 dataset collected in p-pbar collisions at sqrt(s) = 1.96 TeV. The decays analyzed are; B+ -> K+ mu+ mu-, B0 -> K*0(892) mu+ mu-, B0 -> K0_s mu+ mu-, B+ -> K*+(892) mu+ mu-, B0_s -> phi mu+ mu-, and Lambda0_b -> Lambda mu+ mu-. The latter two decays were first observed by CDF in 2011. From an angular analysis of the B -> K* mu+ mu- decays we also present updated results on the transverse polarization and T-odd CP asymmetries reported earlier.
