Title: Spectroscopy and decay properties of the D{sub s} meson

Abstract

Using hydrogenic and Gaussian wave functions, mass spectra and decay properties of the D{sub s}(cs) meson are investigated in the framework of phenomenological quark-antiquark potential (Coulomb plus power) model consisting of a relativistic kinetic energy term. The spin-hyperfine, spin-orbit, and tensor interactions are employed to obtain the pseudoscalar and vector meson masses incorporating the effect of mixing. The decay constants (f{sub P/V}) are computed with QCD correction using the wave function at the origin. The leptonic branching fractions and electromagnetic transition rates are also calculated in this scheme. Our predictions at potential index {nu}=1 are in good agreement with experimental results as well as other theoretical models.
