Abstract
$D^{0}\rightarrow K^{0}_{s}K^{0}_{s}$ is a Singly Cabibbo Suppressed decay, which involves the interference of $c\overline{u}\rightarrow s\overline{s}$ and $c\overline{u}\rightarrow d\overline{d}$ transitions. Due to such interference, the Charge Parity asymmetry may be enhanced to an observable level within the Standard Model. In this work, the signal yield and corresponding raw asymmetry $(A_{raw})$ for $D^{0}\rightarrow K^{0}_{s}K^{0}_{s}$ is estimated using Belle II Monte Carlo samples at integrated luminosity of 1/ab.
