Direct CP asymmetry for B̄0(B0)→K∓π± and B∓→K∓π0 has been measured [1]. The similarity in the two decays suggest AB̄0→K−π+CP∼AB−→K−π0CP. However the asymmetries turned out to be very different. In this work we investigate if this could be a result of physics beyond the Standard Model. A numerical model independent approach is proposed.
