Measurements of sin2Beta at BABAR with charmonium and penguin decays

TL;DR

This paper reports on measurements of CP asymmetries in B meson decays to various final states, using a large data sample from the BABAR experiment, to test the Standard Model's predictions of CP violation.

Contribution

It provides updated measurements of sin2Beta in different decay channels, enhancing the understanding of CP violation in the B meson system.

Findings

Measured sin2Beta in charmonium decays consistent with Standard Model

First measurements of CP asymmetries in penguin-dominated decays

Data sample of approximately 230 million B decays used

Abstract

This article summarises measurements of time-dependent CP asymmetries in decays of neutral B mesons to charmonium, open-charm and gluonic penguin-dominated charmless final states. Unless otherwise stated, these measurements are based on a sample of approximately 230 million Y(4S) to BBbar decays collected by the BABAR detector at the PEP-II asymmetric-energy B-factory.
