abstract
We have evaluated the strong decays of the $K_0^*(1950)$ and $K_0^*(2130)$ within the $^3P_0$ model, by employing the meson wave functions from the relativized quark model. By comparing with the experimental measurements, the $K_0^*(2130)$ could be assigned as $K_0^*(3^3P_0)$, while the $K_0^*(1950)$ seems like an exotic state, because its width can not be reasonably reproduced within the $^3P_0$ model. We also predict that the $K_0^*(2^3P_0)$ state has a mass of about $1811$ MeV and a width of about $656$ MeV, while the $K_0^*(4^3P_0)$ state has a mass of about $2404$ MeV and a width of about $180$ MeV.

Comparing relativistic and non-relativistic quark pair creation models
Relativistic and non-relativistic QPC models produce strong decay width predictions of similar overall quality for light mesons, with the relativistic version exhibiting stronger suppression at high energies.
