| dc.description.abstract | [Abstract] A search for CP violation in D° → π−π+π° 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 D° → K¯π+π° and background regions of the signal mode. The results are consistent with CP symmetry in this decay. | es_ES |
