Abstract

In the framework of relativistic harmonic confinement model for quarks andantiquarks, 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 toget the respective vector-pseudoscalar meson mass differences. Here we employ the same parametrization and model parameters as used in a recent studyof 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.
