Abstract

A precision measurement of the D0 meson mass has been made using ∼281pb-1 of e+e- annihilation data taken with the CLEO-c detector at the ψ(3770) resonance. The exclusive decay D0→KS has been used to obtain M(D0)=1864.847±0.150(stat)±0.095(syst)MeV. This corresponds to M(D0D̄*0)=3871.81±0.36MeV, and leads to a well-constrained determination of the binding energy of the proposed D0D̄*0 molecule X(3872), as Eb=0.6±0.6MeV.
