Abstract
We report a search for CP violation in the decay τ -→π -KS0(0π0)ν τ using a data set of 437×106 τ-lepton pairs, corresponding to an integrated luminosity of 476fb -1, collected with the BABAR detector at the PEP-II asymmetric-energy e +e - storage rings. The CP-violating decay-rate asymmetry is determined to be (-0.36±0. 23±0.11)% approximately 2.8 standard deviations from the standard model prediction of (0.36±0.01)%. © 2012 American Physical Society.
