A Study of Heavy Flavored Mesons with Killingbeck Potential Approach *

In non-perturbative Quantum Chromodynamics (QCD), the formalism of the potential model has proven effective in predicting various static and dynamic properties of heavy-flavored mesons. Within the Schrödinger’s framework, the interaction potential plays a crucial role in determining the meson spectrum. In this work, we incorporate the Killingbeck potential in the Hamiltonian and apply the quantum mechanical variational method to estimate the masses, decay constants, and oscillation frequencies of selected heavy-flavored mesons, using a Coulombic wave function as the trial function. Our results are systematically compared with experimental data and other theoretical findings available in the literature.
