Search for CP violation in the decay D{sup {+-}}{yields}K{sub S}{sup 0}{pi}{sup {+-}}

We report on a search for CP violation in the decay D{sup {+-}{yields}K}{sub S}{sup 0{pi}{+-}} using a data set corresponding to an integrated luminosity of 469 fb{sup -1} collected with the BABAR detector at the PEP-II asymmetric energy e{sup +}e{sup -} storage rings. The CP-violating decay rate asymmetry A{sub CP} is determined to be (-0.44{+-}0.13(stat){+-}0.10(syst))%, consistent with zero at 2.7{sigma} and with the standard model prediction of (-0.332{+-}0.006)%. This is currently the most precise measurement of this parameter.
