1  From a time-dependent analysis of ${{\mathit D}}$ mixing in ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ . This result uses external constraints on R$_{M}$= 1/2 (x${}^{2}$ + y${}^{2}$). Without such constraints, AAIJ 2016F measure $0.0003$ $\pm0.0018$, with a large correlation coefficient to R$_{M}$.
