Measurements of the Branching Fractions of the Singly-Cabibbo-Suppressed Decays $D^0\to \omega \eta$, ${\eta }^{(\prime )}{\pi }^0$ and ${\eta }^{(\prime )}\eta$

Abstract

By analyzing a data sample of 2.93 fb${}^{-1}$ collected at $\sqrt{s}=$ 3.773 GeV with the BESIII detector operated at the BEPCII storage rings, we measure the branching fractions $\mathcal{B}(D^0\to \omega \eta )=(2.15\pm 0.17_{stat.}\pm 0.15_{sys.})\times 10^{-3}$, $\mathcal{B}(D^0\to \eta {\pi }^0)=(0.58\pm 0.05_{stat.}\pm 0.05_{sys.})\times 10^{-3}$, $\mathcal{B}(D^0\to {\eta }^{\prime }{\pi }^0)=(0.93\pm 0.11_{stat.}\pm 0.09_{sys.})\times 10^{-3}$, $\mathcal{B}(D^0\to \eta \eta )=(2.20\pm 0.07_{stat.}\pm 0.06_{sys.})\times 10^{-3}$ and $\mathcal{B}(D^0\to {\eta }^{\prime }\eta )=(0.94\pm 0.25_{stat.}\pm 0.11_{sys.})\times 10^{-3}$. We note that $\mathcal{B}(D^0\to \omega \eta )$ is measured for the first time and that $\mathcal{B}(D^0\to \eta \eta )$ is measured with much improved precision.
