Search for CP violation in the phase space of D0 → π −π +π 0 decays with the energy test
A search for CP violation in D0 → π −π +π 0 decays is reported, using pp collision data collected by the LHCb experiment from 2015 to 2018 corresponding to an integrated luminosity of 6 fb−1 . An unbinned model-independent approach provides sensitivity to local CP violation within the two-dimensiona...

| Sumario: | A search for CP violation in D0 → π −π +π 0 decays is reported, using pp collision data collected by the LHCb experiment from 2015 to 2018 corresponding to an integrated luminosity of 6 fb−1 . An unbinned model-independent approach provides sensitivity to local CP violation within the two-dimensional phase space of the decay. The method is validated using the Cabibbo-favoured channel D0 → K−π +π 0 and background regions of the signal mode. The results are consistent with CP symmetry in this decay. |
