| Résumé : | A study is presented of the reactions K+p→(K+ω)p at 8.25 and 16 GeV/c and K-p→(K-ω)p at 10 and 16 GeV/c and comparison is made with K+ results at 10 GeV/c and K- at 7.3 GeV/c. The (K+ω) and (K-ω) mass spectra both present a strong enhancement very near threshold, while a second peak at ∼1.7 GeV is evident only with incident K- at the lower energies. The threshold peak has very weak energy dependence and is mostly due to the 1+S state which is produced conserving s-channel helicity. It is suggested that this is another decay mode of the resonance Q1(1290) known to decay mainly into Kρ{variant}. The ratio of the Q1 coupling constants to the Kω and Kρ{variant} decay channels, Rω = gKω2/gKρ{variant}2 is determined to be 0.21±0.04. The enhancement at 1.7 GeV is predominantly, but not exclusively, due to the 2- state. While the K+ and K- induced reactions give basically similar results, small differences are observed that can be qualitatively explained in the framework of the Deck model. © 1981. |
