Exclusive semileptonic B decays to excited D mesons
D. Ebert, R. N. Faustov, V. O. Galkin
Exclusive semileptonic B decays to orbitally and radially excited charmed mesons are investigated in the first order of the heavy quark expansion. The emerging leading and subleadi…

Relativistic quark-antiquark potential and heavy quarkonium mass spectra
D. Ebert, R. N. Faustov, V. O. Galkin
A general approach to accounting for retardation effects in the long-range (confining) part of the quark-antiquark potential is presented. The charmonium and bottomonium mass spect…
