Role of t-channel meson exchanges in S-wave πN and KN scatterings
2008
The low-energy S-wave πN and KN scatterings are studied by using the K-matrix approach within the meson exchange framework. The t-channel meson exchanges, especially ρ and σ exchanges, are found to play a very important role in these two processes. The t-channel ρ exchange determines the isospin str...
