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.
Highlights
The Ds meson is a light-heavy quark structure composed of the charm and the strange quark[1]
There exists mutual variation in the masses of 1P states predicted by these models as well as with the experimental measurements
We add separately (in Eq(9)) the spin-dependent part of the usual one gluon exchange potential (OGEP) between the quark anti quark for computing the hyperfine and spin-orbit shifting of the lowlying S, P and D-states
Summary
The Ds meson is a light-heavy quark structure composed of the charm and the strange quark[1]. Mass spectrum as well as many other spectroscopic properties of the Ds meson have been extensively studied in various theoretical schemes[2]. In this paper we employ a potential model scheme that incorporates kinematic relativistic corrections to the kinetic energy term as well as O(1/m) corrections to the potential energy term of the hamiltonian. This allows for an opportunity to test the applicability and validity of such a model to a light-heavy quark bound system.
