Abstract
KN sigma commutator has been calculated in the framework of the (6, \(\bar 6\))+(\(\bar 6\), 6) model. It is found that though this model could not be discarded in favour of the (3, \(\bar 3\))+(\(\bar 3\), 3) or (8, 8) model, a very large value forKN sigma term is required to get a positive value ofπN sigma term.
