Description
The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII)
has accumulated the world's largest e+e- collision samples at ψ(3770)
peak, around the ψ(4040) nominal mass, and at the Λc-pair mass threshold
which allow us to study decays of charmed mesons and baryons in a uniquely
clean background. In this talk, we will review our recent
results including: (1) the extractions of the D(s)+ decay constants, the
form factors of D semi-leptonic decays, and the CKM matrix elements
|Vcs(d)|; (2) the measurements of the strong phase and D 0 D 0 -bar mixing
parameters using quantum coherence; (3) the determinations of the
absolute branching fractions of the hadronic and semi-leptonic decays of
Λc+.
