Search for $CP$ violation in the phase space of $D^0\to {\pi }^{+}{\pi }^{-}{\pi }^{+}{\pi }^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +769

A search for time-integrated $CP$ violation in the Cabibbo-suppressed decay $\mbox{$D^0\rightarrowπ^+π^-π^+π^-$}$ is performed using an unbinned, model-independent technique known…
