The mass spectrum of the kaon family is analyzed by the modified Godfrey–Isgur model with a color screening effect approximating the kaon as a heavy–light meson system. This analysis gives us the structure and possible assignments of the observed kaon candidates, which can be tested by comparing the theoretical results of their two-body strong decays with the experimental data. Additionally, prediction of some partial decay widths is made on the kaons still missing in experiment. This study is crucial to establishing the kaon family and searching for their higher excitations in the future.
