【 摘 要 】

In the framework of relativistic harmonic confinement model for quarks and antiquarks, the masses of 𝑆- and 𝑃-wave mesons and pseudoscalar decay constants from light flavour to heavy flavour sectors are computed. The residual two-body Coulomb interaction and the spin-dependent interaction of the confined one gluon exchange effects (COGEP) such as spin–spin and spin–orbit interactions are perturbatively incorporated with the confinement energy to get the respective vectorpseudoscalar meson mass differences. Here we employ the same parametrization and model parameters as used in a recent study of low-lying hadron masses and leptonic decay widths. The results are being compared with the values obtained from other theoretical models and the experimental values.
