A search for CP violation in the phase space of the decay D+→π−π+π+D+→π−π+π+ is reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The Dalitz plot distributions for 3.1×1063.1×106D+D+ and D−D− candidates are compared with binned and unbinned model-independent techniques. No evidence for CP violation is found.

Abstract
A search for CP violation in the phase space of the decay D+→π−π+π+D+→π−π+π+ is reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The Dalitz plot distributions for 3.1×1063.1×106D+D+ and D−D− candidates are compared with binned and unbinned model-independent techniques. No evidence for CP violation is found.File in questo prodotto:
