Beschreibungen/Notizen

• Results are presented for p → ( ΛK +) dissociation in the reactions K −p → ΛK +K − and and π ±p → ΛK + π ±at 10 and 16 GeV/ c. The cross sections for the low-mass ΛK + enhancement are compatible with the energy dependence σ ∝ p lab −0.3 . The t′ spectra or the ( ΛK +) threshold enhancement are exponential in shape. Its decay angular distribution reveals neither s-channel nor t-channel helicity conservation. The relative probabilities of the processes p → p, p → ( Nπ) I= 1 2 and p → (Λ K +) dissociation are in the ratios 100 : 10 : 0.2, independent of the nature of the incident particle.
