Query: CP violation and material interaction of neutral kaons in measurements
  of the CKM angle $\gamma$ using $B^\pm\to DK^\pm$ decays where $D\to
  K_\text{S}^0\pi^+\pi^-$   As measurements of the CKM angle $\gamma$ in decays of $b$-hadrons become
increasingly precise, it is important to consider the impact of processes that
affect secondary and tertiary decay products and can contribute to the observed
CP violation. 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. Previous studies
determine the impact of kaon CP violation to be a few degrees in size, but make
simplifying assumptions about how experimental measurements are implemented.
These assumptions are lifted in the present study, and the matter regeneration
effect is included for the first time. The results are presented within the
context of $\gamma$ measurements to be made using the LHCb and Belle II II
detectors. It is found that the expected biases due to ignoring the effects of
CP violation and matter regeneration in neutral kaons is small and less than
$0.5^\circ$ degrees in all experimental scenarios considered.
