Abstract

The Λ(1520)\Lambda(1520) resonance is generated dynamically in a unitary coupled channel framework with the πΣ\pi\Sigma^* and KΞK\Xi^* channels in s-wave and πΣ\pi\Sigma and KˉN\bar K N channels in d-wave. The dynamics of this resonance close to and above threshold is then tested through the reactions KpππΛK^-p\to\pi\pi\Lambda and a good agreement with the experimentally measured cross section is observed.
