Heavy hadrons in the relativistic quark model
D. Ebert, R. N. Faustov, V. O. Galkin
Masses of heavy baryons and tetraquarks are calculated in the relativistic quark model using the heavy-quark--light-diquark and diquark-antidiquark approximations, respectively.
Masses of tetraquarks with two heavy quarks in the relativistic quark model
D. Ebert, R. N. Faustov, V. O. Galkin +1
Masses of tetraquarks with two heavy quarks and open charm and bottom are calculated in the framework of the diquark-antidiquark picture in the relativistic quark model. All model…
Masses of excited heavy baryons in the relativistic quark-diquark picture
D. Ebert, R. N. Faustov, V. O. Galkin
The mass spectra of the excited heavy baryons consisting of two light (u,d,s) and one heavy (c,b) quarks are calculated in the heavy-quark--light-diquark approximation within the c…
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…
On The Method of Precise Calculations Of Energy Levels of Hydrogen-like Atoms
N. A. Boikova, Y. N. Tyukhtyaev, R. N. Faustov
We describe a method for deriving logarithmic corrections in the mass ratio to the S-level of a hydrogen-like atom. With this method, a number of new corrections of this type are c…
