The golden decay mode used to measure $\\gamma$ is $B^\\pm\\to DK^\\pm$, where $D\\to K_\\text{S}^0\\pi^+\\pi^-$. Due to the presence of a $K_\\text{S}^0$ meson in the final state, $\\gamma$ measurements based on this mode are affected by neutral kaon CP violation and matter regeneration, and this study examines the potential size of the impact.
