Search for CP Violation using $T$-odd Correlations in $D^0 \to K^+ K^- \pi^+ \pi^-$ Decays

We search for CP violation in a sample of 4.7 x 10{sup 4} Cabibbo suppressed D{sup 0} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -} decays. We use 470 fb{sup -1} of data recorded by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} 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{sup 0} and {bar D}{sup 0} decays. The measured CP violation parameter is A{sub T} = (1.0 {+-} 5.1{sub stat} {+-} 4.4{sub syst}) x 10{sup -3}
