Abstract

We study ⊖+ (1540) production in kaon-nucleon (KN) and nucleon-nucleon (NN) interactions by assuming that the ⊖+ is an isosinglet with JP= 1/2+. Possible t-channel diagrams with K* exchange are considered in both reactions as well as K exchange in NN reactions. The cross section for np→ Λ0+, which has not been considered in previous calculations, is found to be about a factor of 5 larger than that for np→∑0+ due to the large coupling of the KNΛ interaction. The cross sections are obtained by setting gKN⊖ = 1 and varying the ratio of gK*N⊖/gKN⊖ so that future experimental data can be used to estimate these couplings. We also find that the isospin relations hold for these reactions.
