ATLAS测量美介子中的CP破坏和稀有衰变

ATLAS Measurements of CP Violation and Rare Decays in Beauty Mesons

Wolfgang Walkowiak

摘要:

大型强子对撞机(LHC)上的ATLAS实验对中性B介子的混合和CP破坏进行了精确的测量,同时也对电弱FCNC抑制的中性B介子衰变中发生的罕见过程进行了精确的测量。本文主要介绍ATLAS的最新结果,包括稀有过程$B^0_s \to μ^+μ^-$和$B^0 \to μ^+μ^-$的测量,以及$B^0_s \to J/ψϕ$中CP破坏的测量。

英文摘要:

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 $B^0_s \to μ^+μ^-$ and $B^0 \to μ^+μ^-$, and measurements of CP violation in $B^0_s \to J/ψϕ$.
