Decay widths of resonances and pion scattering lengths in a globally invariant sigma model with vector and axial-vector mesons
- We calculate low-energymeson decay processes and pion-pion scattering lengths in a two-flavour linear sigma model with global chiral symmetry, exploring the scenario in which the scalar mesons f0(600) and a0(980) are assumed to be ¯qq states.
