CP Violation in Hadronic Penguins at BABAR

TL;DR

This paper reports preliminary measurements of time-dependent CP violation in various B0 meson decay modes, using the full BABAR dataset of 467 million BBbar pairs, to explore differences in matter-antimatter behavior.

Contribution

It provides new measurements of CP-violation parameters in multiple B0 decay channels, including resonant states, using the complete BABAR dataset.

Findings

Measured CP-violation parameters in several decay modes.

First analysis of certain resonant final states in this context.

Results contribute to understanding matter-antimatter asymmetry.

Abstract

We present preliminary measurements of time-dependent CP-violation parameters in the decays B0->omegaK0S, B0->eta'K0, B0->pi0K0S, B0->phiK0Spi0, and B0->K+K-K0S, which includes the resonant final states phiK0S and f0(980)K0S. The data sample corresponds to the full BABAAR dataset of 467 million BBbar pairs produced at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center.
