${{\mathit D}^{0}}$ $\mathit CP$-VIOLATING DECAY-RATE ASYMMETRIES

This is the difference between ${{\mathit D}^{0}}$ and ${{\overline{\mathit D}}^{0}}$ partial widths for the decay to state ${{\mathit f}}$, divided by the sum of the widths:$
$ $\mathit A_{CP}({{\mathit f}}$) = [$\Gamma $( ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit f}}$) $−$ $\Gamma $( ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)] $/$ [$\Gamma $( ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit f}}$) + $\Gamma $( ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\overline{\mathit f}}}$)].

$\mathit A_{\mathit CP}({{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$) in ${{\mathit D}^{0}}$ , ${{\overline{\mathit D}}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$

 LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13TeV
1  Supersedes AAIJ 2018I. This analysis provides the first complete angular analysis of ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$, and measures angular moments for several bins in the dimuon invariant mass. The mass of the dihadron system is required to be less than 1200 MeV.
