Abstract

A precision determination of the binding energy of the quintessential exotic meson X(3872) as a D⁰D^*0 molecule has been made by means of a precision measurement of mass of D⁰ in its decay into three different modes, D⁰→K_S, K ^±π^±π⁺π-, and K _Sπ⁺π^-. We obtain M(D⁰) = 1864.770±0.024±0.077 MeV, and M(D⁰+D ^*0) = 3871.660±0.176 MeV. This leads to binding energy of B.E.(X(3872)) = M(D⁰+D^*0)-M(X(3872)) = -0.012±0.248 MeV, using the current value of M(X(3872)) = 3871.672±0.174 MeV.
