Decay constants of heavy-light mesons in the relativistic quark model
D. Ebert, R. N. Faustov, V. O. Galkin
Abstract
The decay constants of pseudoscalar and vector heavy-light mesons are calculated in the framework of the relativistic quark model with the completely relativistic treatment of the light quark. It is argued that relativistic effects play a significant role. Good agreement of the model predictions with recent lattice and QCD sum rule calculations as well as available experimental data is found.
