摘要
We have evaluated the strong decays of the K-0*(1950) and K-0*(2130) within the P-3(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(3)P(0)), while the K-0*(1950) is difficult to be explained as the q (q) over bar meson. We also predict that the K-0*(2(3)P(0)) state has a mass of about 1811 MeV and a width of about 656 MeV, while the K-0*(4(3)P(0)) state has a mass of about 2404 MeV and a width of about 180 MeV.
