Resumen

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. [Figure not available: see fulltext.].
