High spin kaons

Type: article

Abstract: The COMPASS Collaboration recently reported the observation of strange-meson spectra in the reaction K − + p → K − π − π + + p and found K 3 and K 4 states, with masses of 2119 ± 1 3 − 12 + 45 MeV and 2210 ± 4 0 − 30 + 80 MeV , respectively. This discovery has significantly renewed interest, prompting a detailed and systematic study of high-spin kaons. In this work, we analyze the mass spectrum and the Okubo-Zweig-Iizuka-allowed two-body strong decay properties of high-spin kaons having J P = 3 ± , 4 ± , and 5 ± within the framework of the modified Godfrey-Isgur model and the P 0 3 model. Moreover, we identify critical decay channels, which may serve as useful guidance for future experimental studies.
