Agreement with experimental data is achieved provided we include the contribution of a κmeson with mass approx. 900 MeV, and a scalar mixing angle (sigma -f_0 mixing in the {|NS>,|S>} basis) varphi_s approx. -14^\circ, as predicted by the model.9 pages, 1 figureHigh Energy Physics - Phenomenologytext
