EVALUATION OF THE πN SIGMA TERM USING DISPERSION RELATIONS-PRESENT STATUS
The dispersion relations are used to perform an analytical continuation of the πN scattering amplitude D + to the Cheng-Dashen point and to calculate the πN sigma term. The dispersion relations were evaluated along two different families of dispersion curves passing through different kinematical regions in the s-channel physical region. The obtained results for the sigma term are still within the error bars of the previous Karlsruhe result.
