• Chiral symmetry breaking andKN sigma commutator

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.

• SU(3)×SU(3) symmetry breaking, (8, 8) Model and theη→3π decay

It is shown that the (8, 8) model and explicitηπ0 mixing successfully explain theη→3π decay width whereas the decay width calculated from the mass difference$$m_{K^ + }^2 - m_{K^0 }^2$$ is about one order less than the experimental value.
