Title: Precision Determination of the D{sup 0} Mass

Abstract

A precision measurement of the D{sup 0} meson mass has been made using {approx}281 pb{sup -1} of e{sup +}e{sup -} annihilation data taken with the CLEO-c detector at the {psi}(3770) resonance. The exclusive decay D{sup 0}{yields}K{sub S}{phi} has been used to obtain M(D{sup 0})=1864.847{+-}0.150(stat){+-}0.095(syst) MeV. This corresponds to M(D{sup 0}D*{sup 0})=3871.81{+-}0.36 MeV, and leads to a well-constrained determination of the binding energy of the proposed D{sup 0}D*{sup 0} molecule X(3872), as E{sub b}=0.6{+-}0.6 MeV.
