Extracting the quark mixing phase {gamma} from B{sup {+-}}{yields}K{sup {+-}}{pi}{sup +}{pi}{sup -}, B{sup 0}{yields}K{sub s}{pi}{sup +}{pi}{sup -}, and B{sup 0}{yields}K{sub s}{pi}{sup +}{pi}{sup -}
We discuss some aspects of the search for CP asymmetry in the three body B decays, revealed through the interference among neighbor resonances in the Dalitz plot. We propose a competitive method to extract the CKM {gamma} angle combining Dalitz plot amplitude analysis of B{sup {+-}}{yields}K{sup {+-}}{pi}{sup +}{pi}{sup -} and untagged B{sup 0}, B{sup 0}{yields}K{sub s}{pi}{sup +}{pi}{sup -}. The method also obtains the ratio and phase difference between the tree and penguin contributions from B{sup 0} and B{sup 0}{yields}K*{sup {+-}}{pi}{sup {+-}} decays and the CP asymmetry between B{sup 0} and B{sup 0}.
