ATLAS Measurements of CP Violation and Rare Decays in Beauty Mesons

Abstract

The ATLAS experiment at the Large Hadron Collider (LHC) has performed accurate measurements of mixing and CP violation in the neutral B mesons, and also of rare processes happening in electroweak FCNC-suppressed neutral B-mesons decays. This contribution focuses on the latest results from ATLAS, including measurements of rare processes $B^0_s \to \mu^+\mu^-$ and $B^0 \to \mu^+\mu^-$, and measurements of CP violation in $B^0_s \to J/\psi\phi$.
