Abstract
We present a search for direct violation in decays. The event sample is selected from of collisions recorded by D0 experiment in run II of the Fermilab Tevatron Collider. The charge asymmetry is obtained using a sample of approximately 40 000 decays. The achieved precision is of the same level as the expected deviation predicted by some extensions of the standard model. We also measured the charge asymmetry .
