Tetraquark nature of the $a_{0} (980)$ meson in hadronic $D$ decays

Hai-Yang Cheng, Cheng-Wei Chiang, Fanrong Xu

The internal structure of the light scalar meson $a_{0} (980)$ is explored in the three-body $D$ decays of $D \to a_{0} (980) P \to P_{1} P_{2} P$ through the intermediate state $a_{0} (980)$ , where…

Updated analysis of $D \to P P, V P$ and $V V$ decays: Implications for $K_{S}^{0} - K_{L}^{0}$ asymmetries and $D^{0}$ - $D^{0}$ mixing

Hai-Yang Cheng, Cheng-Wei Chiang

An updated analysis of the two-body $D \to P P, V P$ and $V V$ decays within the framework of the topological diagram approach is performed. A global fit to the Cabibbo-favored (CF)…
