Decay constants of heavy vector mesons in relativistic Bethe-Salpeter method

In a previous Letter, we computed the decay constants of heavy pseudoscalar mesons in the framework of relativistic (instantaneous) Bethe-Salpeter method (full 0(-) Salpeter equation), in this Letter, we solve the full 1(-) Salpeter equation and compute the leptonic decay constants of heavy-heavy and heavy-light vector mesons. The theoretical estimate of mass spectra of these heavy-heavy and heavy-light vector mesons are also presented. Our results for the decay constants and mass spectra include the complete relativistic contributions. We find F-Ds* approximate to 375 +/- 24, FD* approximate to 340 +/- 23(D-*0, D-*+/-), FBs* 272 +/- 20, F-B* approximate to 238 +/- 18(B-*0, B-*+/-), F-Bc* approximate to 418 +/- 24, F-J/(psi) approximate to 459 +/- 28, F-psi(2S) approximate to 364 +/- 24, F-Upsilon approximate to 498 +/- 20 and Fr-Upsilon(2S) approximate to 366 +/- 27 MeV.
