New Results From BABAR

TL;DR

This paper summarizes recent results from the BABAR experiment, including measurements of CP violation, B mixing, lifetimes, and rare B decays, notably reporting the observation of CP violation in the neutral B system.

Contribution

It provides new experimental measurements of CP violation parameter $ ext{sin}2eta$ and other B meson properties using data from the BABAR detector.

Findings

Measured $ ext{sin}2eta = 0.59 \

Observed CP violation in the neutral B system.

Abstract

The BABAR experiment at the PEP-II asymmetric B factory at SLAC has collected a large sample of data at the $\Upsilon(4S)$ resonance. I will summarize BABAR's new results on CP violation, B mixing and lifetimes, and a selection of rare B decays. In particular, I will describe in detail the measurement of the CP violating parameter $\sin{2\beta}$; BABAR has observed CP violation in the neutral B system finding $\sin{2\beta} = 0.59 \pm 0.14 \pm 0.05$.
