Abstract

A measurement of the phase-space integrated CP-asymmetries of the decays modes $B^{\pm} \to K^{\pm}\pi^{+}\pi^{-}$, $B^{\pm} \to K^{\pm}K^{+}K^{-}$, $B^{\pm} \to \pi^{\pm}K^{+}K^{-}$ and $B^{\pm} \to \pi^{\pm}\pi^{+}\pi^{-}$ is presented. The asymmetries are:

\begin{align} \mathcal{A}_{CP}($B^{\pm} \to K^{\pm}\pi^{+}\pi^{-}$) = +0.004 \pm 0.003, \nonumber \\mathcal{A}_{CP}($B^{\pm} \to K^{\pm}K^{+}K^{-}$) = -0.046 \pm 0.003, \nonumber \\mathcal{A}_{CP}($B^{\pm} \to \pi^{\pm}\pi^{+}\pi^{-}$) = +0.080 \pm 0.006, \nonumber \\mathcal{A}_{CP}($B^{\pm} \to \pi^{\pm}K^{+}K^{-}$) = -0.125 \pm 0.010, \nonumber \end{align}

where the uncertainty is statistical. The analysis uses the LHCb data set collected in 2015, 2016 and 2017 $pp$ collisions, corresponding to an integrated luminosity of $3.71 \,\text{fb}^{-1}$. The distributions of CP asymmetries in the phase space of the four modes are also presented.
