Hadronic Decays of Charmed Hadron

Abstract

The BESIII experiment has collected the $e^{+}{e}^{-}$ collision data samples corresponding to integrated luminosities of 2.93 ${\mathrm{fb}}^{-1}$, $3.19$ ${\mathrm{fb}}^{-1}$, 3.13 ${\mathrm{fb}}^{-1}$ and 567 ${\mathrm{pb}}^{-1}$ at center-of-mass energies of 3.773 GeV, 4.178 GeV, 4.189-4.226 GeV and 4.599 GeV, respectively. We report the measurements of strong-phase parameters based on the decays $D^0\to K_{S/L}^0{\pi }^{+}{\pi }^{-}$, $D^0\to K_{S/L}^0{K}^{+}{K}^{-}$, $D^0\to K^{-}{\pi }^{+}{\pi }^{+}{\pi }^{-}$ and $D^0\to K^{-}{\pi }^{+}{\pi }^0$, which are important input for binned model-independent measurement of the CKM angle $\gamma /{\varphi }_3$. In addition, we report amplitude analyses and branching fraction measurements of $D^{+}$, $D_s^{+}$ and ${\Lambda }_c^{+}$ decays along with the ${\Lambda }_c^{+}$ spin determination.
