Search for CP violation in the decay D+→π−π+π+


LHCb Collaboration; et al; Bernet, R; Müller, K; Steinkamp, O; Straumann, U; Vollhardt, A (2014). Search for CP violation in the decay D+→π−π+π+. Physics Letters B, 728:585-595.

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.
