A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+ → K− K+ π+ in a sample of approximately 370000 decays is carried out. The data were collected by the LHCb experiment in 2010 and correspond to an integrated luminosity of 35 pb^−1. The normalized Dalitz plot distributions for D+ and D− are compared using four different binning schemes that are sensitive to different manifestations of CP violation. No evidence for CP asymmetry is found.

Abstract
A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+ → K− K+ π+ in a sample of approximately 370000 decays is carried out. The data were collected by the LHCb experiment in 2010 and correspond to an integrated luminosity of 35 pb^−1. The normalized Dalitz plot distributions for D+ and D− are compared using four different binning schemes that are sensitive to different manifestations of CP violation. No evidence for CP asymmetry is found.File in questo prodotto:
