Abstract
We present a study of mass spectrum and decay properties of heavy-light mesons in the non-relativistic potential model. We consider a new type of potential for the mesonic system, the combination of harmonic and Yukawa-type potentials. To obtain the wave function of the system, we use the perturbation method. We take the harmonic term as parent and the Yukawa term as perturbation for the generation of wave function for the meson. For calculating the parent wave function, the Nikiforov-Uvarov (NU) approach is used and thereby we obtained a series solution for the perturbative wave function and then reported the total wave function. With this wave function, we then study the mass spectrum, the decay constant, the leptonic and semileptonic decay widths of heavy-light mesons.
