CP violation in $B^{\pm }\to {\pi }^{\pm }{\pi }^{+}{\pi }^{-}$ in the region with low invariant mass of one ${\pi }^{+}{\pi }^{-}$ pair

Recently, the large CP asymmetries in $B^{\pm }\to {\pi }^{\pm }{\pi }^{+}{\pi }^{-}$ decays were found by the LHCb Collaboration to localize in the region $m_{{\pi }^{+}{\pi }^{-}}^2<0.4{\text{GeV}}^2$. We find such larg…
