Two observed structures with M=1868Β±8β57+40β MeV and M=2073Β±94β240+245β MeV are the same states (K2ββ(1980)) in PDG.The analysis
of the mass spectrum and the calculation of the strong decay of K2ββ mesons
support the low mass state of K2ββ(1980) as 23P2β and the high mass state
of K2ββ(1980) as 13F2β in this letter. This analysis brings us very
important criterion for the assignment of the observed K2ββ(1980) and
experimental findings for this assignment is suggested. Additionally,
prediction of some partial decay widths are made on the high excitations of
K2ββ family. This study is crucial to establishing and searching for their
higher excitations in the future.Comment: 9 pages, 6 figures. arXiv admin note: text overlap with
