Abstract

The differential cross section for η production in reaction π-p→ηn has been measured over the full angular range at seven incident π- beam momenta from threshold to pπ-=747 MeV/c using the Crystal Ball multiphoton spectrometer. The angular distributions are S wave dominated. At 10 MeV/c above threshold, a small D-wave contribution appears that interferes with the main S wave. The total η production cross section σtot is obtained by integration of dσ/dΩ. Starting at threshold, σtot rises rapidly, as expected for S-wave-dominated production. The features of the π-p→ηn cross section are strikingly similar to those of the SU(3) flavor-related process K-p→ηΛ. Comparison of the π-p→ηn reaction is made with η photoproduction.
