Charmless b-hadrons decays at CDF

TL;DR

This paper reports on measurements of branching fractions and CP asymmetries in charmless b-hadron decays at CDF, including first observations of several decay modes, providing insights into CP violation and hadron decay processes.

Contribution

It presents the first observations and measurements of specific charmless b-hadron decay modes and their CP asymmetries using 1fb^{-1} of data at CDF.

Findings

First observation of Bs->Kpi, Lb->ppi, Lb->pK decay modes

Measured branching fractions for these decay modes

Reported direct CP asymmetries for the observed decays

Abstract

We present CDF results on the branching fractions and time-integrated direct CP asymmetries for Bd, Bs and Lb decay modes into pairs of charmless charged hadrons (pions, kaons and protons). The data-set for these measurements amounts to 1fb^{-1} of pbar-p collisions at a center of mass energy 1.96TeV. We report on the first observation of the Bs->Kpi, Lb-ppi and Lb->pK decay modes and on the measurement of their branching fractions and direct CP asymmetries.
