Search for $D^{+}\to K^{-}{K}_s^0{\pi }^{+}{\pi }^{+}{\pi }^0$ at Belle

Abstract

We search for the singly Cabibbo-suppressed decay $D^{+}\to K^{-}{K}_s^0{\pi }^{+}{\pi }^{+}{\pi }^0$ using the full data set of 988 fb${}^{-1}$ recorded by the Belle experiment at the KEKB $e^{+}{e}^{-}$ collider. We measure the branching fraction for this decay to be $\left(6.4_{-3.8}^{+3.9}\right)\times 10^{-5}$ with an upper limit at 95% credibility of $1.4\times 10^{-4}$. We also measure the sum of the branching fractions for $D^{+}\to {\bar{K}}^{\ast }\eta {\pi }^{+}$ and $D^{+}\to {\bar{K}}^{\ast }\omega {\pi }^{+}$ to be $\left(6.0_{-5.8}^{+6.3}\right)\times 10^{-5}$ with an upper limit at 95% credibility of $1.8\times 10^{-4}$.
