K oSK oL production by e +e - annihilation at φ energy
Abstract
Data have been taken at the φ energy with the same large solid angle detector which has been used for the measurement of the ϱ and ω production by e +e - annihilations. From the φ→ KoLKoSπ+ φ- excitation curve we have deduced the φ width Γφ = (3.81 ± 0.37) MeV and the cross-section σe+e- → KoLKoS = (1.48±0.08±0.12) μb. (the quoted errors are respectively statistical and systematical.)
