Search for CP violation in $D^0\to {\pi }^{-}{\pi }^{+}{\pi }^0$ decays with the energy test

LHCb collaboration, R. Aaij, B. Adeva +703

A search for time-integrated CP violation in the Cabibbo-suppressed decay $D^0\to {\pi }^{-}{\pi }^{+}{\pi }^0$ is performed using for the first time an unbinned model-independent technique known as t…
