Charm physics at BESIII

BESIII has taken 2.93, 7.33 and 4.5fb−1 of e+e− collision data at energies of 3.773, 4.128-4.226 and 4.6-4.7 GeV, collecting the world largest dataset of of DD ̄, DsD ̄s∗ and Λ+c Λ ̄−c pairs. On the subject of charmed meson, we report the first experimental measurement of weak decay of charmed vector meson D∗+ → e+ν , the updated measurements of |Vcs| in Ds+ → τ+ντ,τ+ → μ+νμν ̄τ and the form factor study in Ds+ → π+π−e+νe. In addition, we report the first amplitude analyses of Ds+ → KS0K+π0 including the observation of a new a0-like state with mass of 1.817 GeV/c2 and the improved measurement of the strong-phase difference in quantum-correlated D0D ̄0 decays. On the subject of charmed baryon, we report the form factor measurement in Λ+c → Λe+νe and the observation of Λ+c → pK−e+νe. Moreover, we report the first amplitude analysis of Λ+c → Λπ+π0 and the studies of Cabibbo-suppressed Λ+c → Σ0K+ and Σ+K0 decays. Finally, we present the prospect on measurements of charmed meson hadronic decays with the coming 20 fb−1 of data being collected at 3.773 GeV by BESIII.
