On the Measurement of the Unitarity Triangle Angle gamma from B^0 -> DK^{*0} Decays

Abstract

The decay B^0 -> DK^{*0} is well-known to provide excellent potential for a precise measurement of the Unitarity Triangle angle gamma in future experiments. It is noted that the sensitivity can be significantly enhanced by studying the amplitudes relative to those of the flavour-specific decay B^0 -> D_2^{*-}K^+, which can be achieved by analyzing the B^0 -> D\pi^-K^+ Dalitz plot.
