Findings

First polarization measurement of B_s^0 → φφ decay.

Updated analysis of B^0_(s) → h^+h'^- decays.

Insights into penguin transitions relevant for New Physics searches.

Abstract

Penguin transitions play a key role in the search of New Physics hints in the heavy flavor sector. During the last decade CDF has been exploring this opportunity with a rich study of two--body charmless decays of neutral B mesons into charged final--state particles. After briefly introducing the aspects of this physics peculiar to the hadron collision environment, I report on two interesting results: the first polarization measurement of the B^0_s --> phi phi decay and the update of the B^0(_s) --> h^+h'^- decays analysis.
