Abstract

An integrated luminosity of 2.9 fb − 1 data had been collected at s = 3.773 GeV by May of 2011 with the BESIII detector at the BEPCII collider, which makes it possible to systematically study the properties of the semileptonic, leptonic and hadronic decays of the charmed mesons. With the data, many high precise measurements including the CKM matrix elements and the form factors, the decay constants, as well as the topics related to hadronic decays such as absolute branching fractions, searches for CP violations and Dalitz plot analyses are being studied at the BESIII. All these analyses are expected to be accomplished in the near future.
