Study of various spectroscopic properties of the Ds meson

Spectroscopic parameters of the Ds(c ¯) meson are obtained using phenomeno- logical quark antiquark potential(coulomb plus power) model consisting of O (1/m) cor- rection to the potential. Within Variational scheme Gaussian wave function is employed with a hamiltonian incorporating kinematic relativistic corrections to obtain various prop- erties such as the mass spectra, decay constants, electromagnetic transitions. The results are compared with various experimental measurement as well as other theoretical predic- tions.
