Masses and weak decay rates of doubly heavy baryons
D. Ebert, R. N. Faustov, V. O. Galkin +1
Mass spectra and semileptonic decay rates of doubly heavy baryons are studied in the framework of the relativistic quark model in the quark-diquark approximation.
Weak decays of the B_c meson
D. Ebert, R. N. Faustov, V. O. Galkin
Semileptonic and nonleptonic decays of the B_c meson are studied in the framework of the relativistic quark model. The heavy quark expansion in inverse powers of the heavy (b,c) qu…
Heavy quarkonium hyperfine structure and leptonic decays
D. Ebert, R. N. Faustov, V. O. Galkin
The relation between the hyperfine structure and leptonic decay rates of heavy quarkonia is considered with the account of relativistic and radiative corrections. The calculated de…
Exclusive weak B decays to excited meson states
D. Ebert, R. N. Faustov, V. O. Galkin
Exclusive semileptonic B decays to radially excited charmed mesons and rare radiative B decay to the orbitally excited tensor K_2^*(1430) meson are investigated in the framework of…
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…
