Description
The BESIII Experiment at the Beijing Electron Positron Collider
(BEPCII) accumulated the world's largest e+e- collision samples
at Ecm = 3.773, 4.009, 4.18 GeV. Based on analyses of D(s)+ to l+v
(l=mu, tau), D -> K(pi)l+v (l=e or mu), D+ -> K-pi+e+v, D0(+) ->
f0(980)e+v, Ds+ -> eta(')e+v, we report the determinations of CKM
matrix elements |Vcs(d)|,the D(s)+ decay constants, the form factors
of D semi-leptonic decays. These are important to calibrate the LQCD
calculations of decay constant and form factors and to test the CKM
unitarity. Using the quantum correlation property of D0D0-bar
production, we determine the parameters of the strong phase difference
and D0D0-bar mixing. We will also report some preliminary results for
Ds+ decays to omega pi+,omega K+ and pn.
