The energy dependence of the pp->pK+Lambda/Sigma0 cross sections close to the Sigma production thresholds


It is proposed to measure simultaneously both, the total cross section of the Sigma0 production in the p+p interaction and the momentum spectra of kaons produced in the pp->pK+Lambda reaction in the vicinity of the Sigma thresholds, in order to observe possible cusp effects caused by coupling between Lambda and Sigma baryons.
