| 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.
