Abstract: The angle γ of the standard CKM unitarity triangle can be determined from B → DK 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 γ determination is to introduce a shift |δγ| ≲ $ \mathcal{O}\left( {1{0^{-7 }}} \right) $ , well below any present or planned future experiment.
