英文摘要 | We report on measurements of the differential cross section d sigma/d Omega and the first measurement of the analyzing power A(y) in the Delta(1232) excitation energy region of the reaction pp -> {pp}(s)pi(0) where {pp}(s) is a S-1(0) proton pair. The experiment has been performed with the ANKE spectrometer at COSY-Julich. The data reveal a peak in the energy dependence of the forward {pp}(s) differential cross section, a minimum at zero degrees of its angular distribution, and a large analyzing power. The results present a direct manifestation of two two-baryon resonance-like states with J(P) = 2(-) and 0(-) and an invariant mass of 2.2 GeV/c(2). |
