Abstract

Two observed structures with M=1868±857+40M=1868 \pm 8^{+ 40}_{- 57} MeV and M=2073±94240+245M=2073 \pm 94^{+ 245}_{- 240} MeV are the same states (K2(1980)K_2^*(1980)) in PDG.The analysis of the mass spectrum and the calculation of the strong decay of K2K_2^* mesons support the low mass state of K2(1980)K_2^*(1980) as 23P22^3P_2 and the high mass state of K2(1980)K_2^*(1980) as 13F21^3F_2 in this letter. This analysis brings us very important criterion for the assignment of the observed K2(1980)K_2^* (1980) and experimental findings for this assignment is suggested. Additionally, prediction of some partial decay widths are made on the high excitations of K2K_2^* family. This study is crucial to establishing and searching for their higher excitations in the future.
