Description
The Belle and Belle II experiments have collected a $1.6$ ab$^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. These samples contain a large number of $e^+e^-\to c\bar{c}$ events that produce charmed mesons. We present measurements of charm-mixing parameters from flavour-tagged $D^0\to K^0_{\rm S}\pi^+\pi^-$ decays. Direct $C\!P$ violation is searched for in $D^0\to K^0_{\rm S}K^0_{\rm S}$ decays and $D$ meson decays to two or three pions.
