SUMMARY
The discussion focuses on the definitions of scalar-isoscalar and non-scalar-isoscalar channels in the context of pion quasi-elastic scattering. Scalar-isoscalar channels refer to states where two pions are in an isotopic spin 0 state (scalar) and can have angular momentum J=0. In contrast, non-scalar-isoscalar channels involve isotopic spin 1 states (non-scalar) and can have angular momentum J=1 or higher. The conversation clarifies that for pi-N scattering, the terms scalar and non-scalar pertain to even and odd orbital angular momentum (L), rather than isospin characteristics.
