Charm Physics at BESIII

Recently, BESIII has performed many analyses with the largest e(+)e(-) annihilation data set taken on the mass-thresholds. Those works focus on the measurements of the CKM matrix elements vertical bar V-cd(s)vertical bar, the transition form factors f(D(s)), tests of lepton flavor universality, precise measurements of branching fraction, studies of interesting intermediate states in the multiple-body decays, and searchs for the new physics. Among those, we present the results with three categorities, the (semi-) leptonic decays, hadronic decays, and the rare decays.
