Anti-kaon induced reactions on the nucleon

Using a previously established effective Lagrangian model we describe anti-kaon induced reactions on the nucleon. The dominantly contributing channels in the c.m.-energy region from threshold up to 1.72 GeV are included $(\overline{K}N,\pi \Sigma ,\pi \Lambda ).\mathrm{}$ We solve the Bethe-Salpeter equation in a unitary K matrix approximation.
