Precision Measurement of the Branching Fraction of D^{+}→μ^{+}ν_{μ}.

Using 20.3  fb^{-1} of e^{+}e^{-} collision data collected at a center-of-mass energy of E_{c.m.

Observation of the W-Annihilation Process D_{s}^{+}→ωρ^{+} and Measurement of D_{s}^{+}→ϕρ^{+} in D_{s}^{+}→π^{+}π^{+}π^{-}π^{0}π^{0} Decays.

We present the first amplitude analysis and branching fraction measurement of the decay D_{s}^{+}→π^{+}π^{+}π^{-}π^{0}π^{0}, using e^{+}e^{-} collision data collected with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV corresponding to an integrated luminosity of 7.

Observation of an Axial-Vector State in the Study of the Decay ψ(3686)→ϕηη^{'}.

Using (2712.4±14.3)×10^{6} ψ(3686) events collected with the BESIII detector at BEPCII, a partial wave analysis of the decay ψ(3686)→ϕηη^{'} is performed with the covariant tensor approach.

Evidence for Two Excited Ω^{-} Hyperons.

Using e^{+}e^{-} collision data corresponding to an integrated luminosity of 19  fb^{-1} collected by the BESIII detector at center-of-mass energies ranging from 4.13 to 4.70 GeV, we report the first evidence for a new excited Ω^{-} hyperon, the Ω(2109)^{-}, through the process e^{+}e^{-}→Ω(2109)^{-}Ω[over ¯]^{+}+c.

Observation of D^{+}→η^{'}μ^{+}ν_{μ} and First Experimental Study of D^{+}→η^{'}ℓ^{+}ν_{ℓ} Decay Dynamics.

Using 20.3  fb^{-1} of e^{+}e^{-} collision data collected at the center-of-mass energy 3.773 GeV with the BESIII detector, we report the first observation of the semileptonic decay D^{+}→η^{'}μ^{+}ν_{μ} with significance of 8.
