Measurement of the anomalous like-sign dimuon charge asymmetry with 9 fb$^{-1}$ of $p \bar{p}$ collisions

TL;DR

This paper reports a measurement of the anomalous like-sign dimuon charge asymmetry using 9 fb$^{-1}$ of proton-antiproton collision data, aiming to investigate potential signs of new physics beyond the Standard Model.

Contribution

It provides a new, precise measurement of the asymmetry, complementing previous results and enhancing the understanding of CP violation in the B meson system.

Findings

Measurement of the asymmetry with improved precision

Results consistent or inconsistent with Standard Model predictions

Implications for new physics scenarios

Abstract

The D\O\ Collaboration has performed a new measurement of the anomalous like-sign dimuon charge asymmetry with 9 fb$^{-1}$ of $p \bar{p}$ collisions. In these proceedings I present a short overview of the measurement that complements the slides presented at the DPF-2011 Conference.
