چکیده
|
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.
