| Abstract | We present the first amplitude analysis of the decay $D^{+}_{s} \rightarrow \pi^{+}\pi^{0}\eta$. We use an $e^{+}e^{-}$ collision data sample corresponding to an integrated luminosity of 3.19~${\mbox{\,fb}^{-1}}$ collected with the BESIII detector at a center-of-mass energy of $4.178$ GeV. We observe for the first time the pure $W$-annihilation decays $D_{s}^{+} \rightarrow a_{0}(980)^{+}\pi^{0}$ and $D_{s}^{+} \rightarrow a_{0}(980)^{0}\pi^{+}$. We measure the absolute branching fractions $\mathcal{B}(D_{s}^{+} \rightarrow a_{0}(980)^{+(0)}\pi^{0^(+)}, a_{0}(980)^{+(0)} \to \pi^{+(0)}\eta) = (1.46\pm0.15_{{\rm stat.}}\pm0.23_{{\rm sys.}})$\%, which is larger than the branching fractions of other measured pure $W$-annihilation decays by at least one order of magnitude. In addition, we measure the branching fraction of $D_{s}^{+} \rightarrow \pi^{+}\pi^{0}\eta$ with significantly improved precision. |
