Charmless b-hadron decays at CDF

TL;DR

This paper reports measurements of branching fractions and CP asymmetries in charmless b-hadron decays at CDF, including rare decay rates and CP violation, using data from the Fermilab Tevatron.

Contribution

It provides new measurements of decay rates and CP asymmetries in charmless b-hadron decays, including rare decay modes, from the upgraded CDF detector.

Findings

Measured branching fractions for B0, Bs, and Lambda_b decays.

Observed CP-violating asymmetries in certain decay channels.

Reported limits on rare decay processes like B0, Bs --> mu+ mu-.

Abstract

I present recent results of measurements of branching fractions and CP-violating asymmetries in B0, Bs, and Lambda_B two-body charmless decays at the upgraded Collider Detector at the Fermilab Tevatron. Measurements of rates of flavor-changing neutral current B0, Bs -->mu+mu- and B+/B0/Bs --> mu+mu- K+/K*0/phi decays are also reported. The results are extracted from samples corresponding to time-intergrated luminosities ranging from 0.78 to 1 fb-1.
