Description
We have obtained a sample of 20 465 (2201) events in the channel pp -> (Λ0K+)p at 50 (30) GeV/c incident momentum with the Geneva-Lausanne spectrometer at the CERN SPS. In this analysis we investigate: (I) the production of Nsup(*)(I=1/2) states in the mass region 1.6 <= M (Λ0K+) <= 2.6 GeV and momentum transfer 0.06 <= vertical stroketvertical stroke1.0 (GeV/c)2, by studing the amplitudes and phases from a moment analysis of the decay angular distribution; (II) the contribution of the K-exchange Deck model for M(Λ0K+) < 2.22 GeV; (III) the double Regge exchange phenomenology for ssub(Λ)0sub(K)+ > 5 GeV2 and ssub(K)+sub(p) > 5 GeV2.
