Abstract

The angle gamma of the standard CKM unitarity triangle can be determined from B -> D K decays with a very small irreducible theoretical error, which is only due to second-order electroweak corrections. We study these contributions and estimate that their impact on the gamma determination is to introduce a shift |delta gamma| <~ O(10^-7), well below any present or planned future experiment.
