Abstract:
|
We search for C P 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. C P violation is searched for in the difference between the T -odd asymmetries, obtained using triple product correlations, measured for D 0 and ¯¯¯ D 0 decays. The measured C P violation parameter is A T = ( 1.0 ± 5.1 stat ± 4.4 syst ) × 10 − 3 . |
