Measurement of CP Observables in B to D0 K Decays at CDF

TL;DR

This paper reports the first measurement of CP observables R_cp and A_cp in B- to D0 K- decays at a hadron collider, using data from the CDF II detector, contributing to understanding CP violation related to the CKM angle gamma.

Contribution

It provides the first measurement of these CP observables at a hadron collider in this decay mode, aligning with previous results from Belle and BABAR.

Findings

Results are consistent with Belle and BABAR measurements.

First hadron collider measurement of these CP observables.

Supports the Standard Model's description of CP violation.

Abstract

This paper describes the determination of the direct CP observables R_cp and A_cp, related to the CKM angle gamma, using B- to D0 K- decays in 1.0 inverse fb of data collected with the CDF II detector. This is the first measurement of these CP observables made at a hadron collider in this decay mode. The results presented are consistent with the measurements of these quantities made by the Belle and BABAR collaborations.
