1. Measurement of time integrated raw asymmetry in D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}}$ decay at Belle II / Sanjeeda Bharati Das ; Kavita Lalwani [BELLE2-CONF-PROC-2023-048]
27 December 2023

$D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}$ 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. [...]

3. Measurement of raw asymmetry in $D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}$ decay at Belle II / Sanjeeda Bharati Das ; Kavita Lalwani [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.

4. Measurement of time-integrated raw asymmetry in D0->K^{+}K^{−} decay / Sanjeeda Bharati Das1, ; Kavita Lalwani ; Angelo Di Canto [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. [...]
