New measurement of D0 and D+ meson masses with the KEDR detector

Using the 4.9 pb${}^{-1}$ statistics collected at the peak of the $\psi (3770)$ resonance with the KEDR detector at the VEPP-4M electron-positron collider, we measured the masses of the neutral and charged D mesons: $M_{D^0}=1865.100\pm 0.210(stat)\pm 0.046(syst)MeV,$ and $M_{D^{+}}=1869.560\pm 0.288(stat)\pm 0.109(syst)MeV$.
