    • 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.
