      abstract     = {The extraction of hadron-hadron scattering parameters from
                      lattice data by using the Lüscher approach becomes
                      increasingly complicated in the presence of inelastic
                      channels. We propose a method for the direct extraction of
                      the complex hadron-hadron optical potential on the lattice,
                      which does not require the use of the multi-channel Lüscher
                      formalism. Moreover, this method is applicable without
                      modifications if some inelastic channels contain three or
                      more particles.},
