Abstract

We report on a search for direct CP violation in the singly Cabibbo-suppressed decay D+ -> K+K-pi(+/-) using a data sample of 476 fb(-1) of e(+)e(-) annihilation data accumulated with the BABAR detector at the SLAC PEP-II electron-positron collider, running at and just below the energy of the Upsilon(4S) resonance. The integrated CP-violating decay rate asymmetry A(CP) is determined to be (0.37 +/- 0.30 +/- 0.15)%. Model-independent and model-dependent Dalitz plot analysis techniques are used to search for CP-violating asymmetries in the various intermediate states. We find no evidence for CP-violation asymmetry. DOI: 10.1103/PhysRevD.87.052010
