We report the first reconstruction in hadron collisions of the suppressed decays B-2!D(2!K+[pi]- )K- and B-2!D(2!K+[pi]- )[pi]- decays, sensitive to the CKM phase [gamma], using data from 7 fb-1 of integrated luminosity collected by the CDF II detector at the Tevatron collider. We reconstruct a signal for the B-2!D(2!K+[pi]- )K- suppressed mode with a significance of 3.2 standard deviations, and measure the ratios of the suppressed to favored branching fractions R(K) = [22.0 " 8.6(stat) " 2.6(syst)] x 10-3, R+(K) = [42.6 " 13.7(stat) " 2.8(syst)] x 10-3, R-(K) = [3.8 " 10.3(stat) " 2.7(syst)] x 10-3 as well as the direct CP-violating asymmetry A(K) = -0.82"0.44(stat)"0.09(syst) of this mode. Corresponding quantities for B- 2!D(2!K+[pi]- )[pi]- decay are also reported.

Using a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II B Factory in 1999-2004, they study B{sup -} {yields} K{sup 0}K*(892){sup -} decays where K*{sup -} {yields} K{sub S}{sup 0} {pi}{sup -} and D{sup 0} {yields} K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup 0}, K{sup -}{pi}{sup +}{pi}{sup +}{pi}{sup -} (non-CP final states); K{sup +}K{sup -}, {pi}{sup +}{pi}{sup -} (CP+ eigenstates); K{sub S}{sup 0}{pi}{sup 0}, K{sub S}{sup 0}{phi} and K{sub S}{sup 0}{omega} (CP- eigenstates). They measure four observables that are sensitive to the angle {gamma} of the CKM unitarity triangle; the partial-rate charge asymmetries A{sub CP{+-}} and the ratios of the B-decay branching fraction in CP{+-} and non-CP decays R{sub CP{+-}}: A{sub CP+} = -0.08 {+-} 0.19 (stat.) {+-} 0.08 (syst.); A{sub CP-} = -0.26 {+-} 0.40 (stat.) {+-} 0.12 (syst.); R{sub CP+} = 1.96 {+-} 0.40 (stat.) {+-} 0.11 (syst.); R{sub CP-} = 0.65 {+-} 0.26 (stat.) {+-} 0.08 (syst.).
