Description
The study of light quark mesons plays a significant role both theoretically and experimentally. In the present work, the mass-spectra of the light mesons ($u\bar{s}$ and $s\bar{s}$) is systematically studied within the framework of Regge phenomenology. Several relations between Regge slope, intercept, and meson masses are extracted with the assumption of linear Regge trajectories. Using these relations ground state masses ($1^{2}S_{0}$and $1^{3}S_{1}$) of the pure $s\bar{s}$ states are evaluated. Further, the Regge slopes for $1^{2}S_{0}$and $1^{3}S_{1}$ trajectories are extracted in the ($J,M^{2}$) plane to obtained the orbitally excited state masses for these mesons. Similarly, the values of Regge parameters are calculated in the in the ($n,M^{2}$ ) plane for each Regge lines and the obtained the radially excited state masses of mesons lying on that Regge trajectory. The main purpose to study the $s\bar{s}$ meson is that some of the reported exotic states may be the excited or mixed state of strangeonia. The obtained mass spectra could provide useful information in the future experimental searches.
