Abstract

The production of the f⁰ (1270) has been studied in the reaction π^-p → π⁺π^-n at 12 and 15 GeV/c in the momentum transfer range 0.02 to 0.80 GeV². Differential and total cross sections for the reaction π^-p → f⁰n have been determined. The f⁰ decay density matrix elements have been evaluated requiring all the matrix eigenvalues to be non-negative. The relative unnatural and natural parity exchange contributions to the f⁰ production have been studied. The results are compared with a Regge exchange model formulated in terms of the pion and A₂ exchanges including cut contributions.
