Structure in π^+p elastic backward scattering

The energy dependence of the differential cross section for π^+p elastic scattering at a c.m. angle near 174^o has been measured. The momentum range of incident π^+ was 2.06-4.70 GeV/c. On this energy dependence one can see a structure, i.e. maxima corresponding to the baryon resonances Δ (2420) and...

The energy dependence of the differential cross section for π^+p elastic scattering at a c.m. angle near 174^o has been measured. The momentum range of incident π^+ was 2.06-4.70 GeV/c. On this energy dependence one can see a structure, i.e. maxima corresponding to the baryon resonances Δ (2420) and Δ (2840). The structurte is used for determination of the parities of these resonances. Ausführliche Beschreibung
