Measurement of the CKM angle γ using B ± → DK ± with D → K S0 π + π −, K S0 K + K − decays
A binned Dalitz plot analysis of B± → DK± decays, with D → KS0π+π− and D → KS0K+K−, is used to perform a measurement of the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle γ. The analysis is performed without assuming any D decay model, through the use of information on the strong-phase variation over the Dalitz plot from the CLEO collaboration.
