dc.descriptionWe present B_c-meson two-point sum rules at next-to-leading order in NRQCD approximation. Analitycal results for perturbative spectral density and gluon condensate contribution with account for summed Coulomb corrections are given. Estimates of various c-quark masses together with couplings and masses of lowest lying B_c-meson resonances are performed.
