$D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}$ is a Singly Cabibbo Suppressed decay, which involves the interference of $c\overline{u}\longrightarrow s\overline{s}$ and $c\overline{u}\longrightarrow d\overline{d}$ transitions. [...]

[BELLE2-CONF-PROC-2023-033]
15 September 2023
The decay $D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}$ is a singly Cabibbo-suppressed transition that involves the interference between $c\overline{u}\longrightarrow s\overline{s}$ and $c\overline{u}\longrightarrow d\overline{d}$ amplitudes, mediated by the exchange of a W boson at the tree level, that can generate CP asymmetries at the 1% level, even if the Cabibbo-Kobayashi-Maskawa phase is the only source of CP.

[BELLE2-CONF-PROC-2023-022]
10 July 2023
Current experimental measurements of the CP asymmetry (ACP ) in D0 -> K0s Ks0 decay are limited by the statistical precision, with the best measurement performed by Belle experiment using 921 fb−1 of data. [...]

/ Manish Kumar ; Kavita Lalwani ; Karim Trabelsi
[BELLE2-CONF-PROC-2019-008]
08 July 2019
We present a preliminary study of using the decay $B^{\pm} \rightarrow D_{CP}K^{\pm}$ to measure $\phi_{3}$ at Belle II, where $D_{CP}$ represents a $D$ meson decay to a $CP$ even eigenstate i.e. [...]
