Study of various spectroscopic properties of the Ds meson

Abstract

Spectroscopic parameters of the Ds (cs̄) meson are obtained using phenomenological quark antiquark potential(coulomb plus power) model consisting of O(1/m) correction to the potential. Within Variational scheme Gaussian wave function is employed with a hamiltonian incorporating kinematic relativistic corrections to obtain various properties such as the mass spectra, decay constants, electromagnetic transitions. The results are compared with various experimental measurement as well as other theoretical predictions.
