CP Violation in Hadronic B Decays at CDF

TL;DR

This paper presents precise measurements of CP violation, mixing parameters, and branching ratios in b-hadron decays from the CDF experiment, providing tests of the Standard Model in proton-antiproton collisions.

Contribution

It reports the final CDF results on CP asymmetries, mixing phase bounds, and branching ratios in various b-hadron decays, improving precision and consistency with the Standard Model.

Findings

CP asymmetries measured with high precision

Bounds set on Bs mixing phase and decay width difference

Branching ratios of Bs decays updated and consistent with Standard Model

Abstract

I report recent measurements in b-hadron decays reconstructed in the full data set of \sqrt{s} = 1.96 TeV proton-antiproton collisions collected by the CDF experiment at the Tevatron. These include the final CDF results on: measurements of CP asymmetries in two-body charmless decays of the Bd, Bs, and \Lambda^0_b hadrons; bounds on the Bs mixing phase and on the decay width difference of Bs mass eigenstates; and updated measurements of branching ratios of Bs->Jpsi Phi and Bs->Ds(*)Ds(*) decays. All measurements are among the most precise from a single experiment and in agreement with the standard model predictions.
