Mass spectrum of S-wave mesons in the relativistic independent quark model

Abstract

The confining strength or model parameters and constituent quark masses are reparametrized for predicting the ground state meson masses. We analyzed these from the hyperfine splitting of $S$-wave heavy-flavored, heavy-light and light (except non-strange) mesons in the framework of a relativistic independent quark (RIQ) model with one gluon exchange and centre-of-mass correction. These mesons with spin parity $J^P=0^{-}$ and $1^{-}$, the masses obtained are in accordance with the experimental physical masses. The results will serve as good complementary tools in further study of hadron dynamics and will behave as a foundation for the higher excited and exotic states of hadrons.
