The Dependence of the "experimental" Pion Nucleon Sigma Term on Higher Partial Waves
A dependence of the value of the pion-nucleon sigma term on higher partial waves is discussed. Two recent predictions of a high value of sigma term are scrutinezed. It has been concluded that the main reason for obtaining high values of the sigma term are input D waves that are not consistent with analyticity.
