Summary:

We present for the first time a measurement of the weak phase 2β + γ obtained from a time-dependent Dalitz plot analysis of B° → D{sup ∓}K°π{sup ±} decays. Using a sample of approximately 347 x 10⁶ B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy storage rings, we obtain 2β + γ = (83 ± 53 ± 20)° and (263 ± 53 ± 20){sup o} assuming the ratio r of the b → u and b → c decay amplitudes to be 0.3. The magnitudes and phases for the resonances associated with the b → c transitions are also extracted from the fit.
