Mass spectra and decay constants of heavy-light mesons: a case study of QCD sum rules and quark model (Q1626110)

Summary: We visited mass spectra and decay constants of pseudoscalar and vector heavy-light mesons (\(B\), \(B_s\), \(D\), and \(D_S\)) in the framework of QCD sum rule and quark model. The harmonic oscillator wave function was used in quark model while a simple interpolating current was used in QCD sum rule calculation. We obtained good results in accordance with the available experimental data and theoretical studies.
