Abstract

We search for CP violation in a sample of 4.7×10^4 Cabibbo suppressed D^0→K^+K^-π^+π^- decays. We use 470  fb^(-1) of data recorded by the BABAR detector at the PEP-II asymmetric-energy e^+e^- storage rings running at center-of-mass energies near 10.6 GeV. CP violation is searched for in the difference between the T-odd asymmetries, obtained using triple product correlations, measured for D^0 and D[overbar]^0 decays. The measured CP violation parameter is A_T=(1.0±5.1_(stat)±4.4_(syst))×10^(-3).
