Threshold Behaviour of Meson-Nucleon-S11(1535) Vertexfunctions and Determination of the S11(1535) Mixing Angle
F. Kleefeld
Abstract
A new method for the determination of the spin-1/2-3/2-mixing angle and the range parameter of the quarkmodel wavefunction of the resonance S-11(1535) is presented. The method ist based on a quantitative calculation of the total cross section of pp ppη at threshold. The quantitative on-shell treatment of ISI and FSI is discussed.
