Abstract

A search for CP violation in the phase space of the decay 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 × 106 D+ and D- candidates are compared with binned and unbinned model-independent techniques. No evidence for CP violation is found. © 2013 The Authors.
