For coupled-channel systems, the trapped integrated correlation function difference converges to a weighted integral over the sum of the two channel phase shifts, independent of inelasticity.

abstract
This is the "preprint" for a paper that came out in 1998 but for some reason wasn't posted then. Abstract:These lectures are for novices to lattice QCD. They introduce a set of simple ideas and numerical techniques that can be implemented in a short period of time and that are capabable of generating nontrivial, nonperturbative results from lattice QCD. The simplest of these calculations can be completed on a standard workstation or high-end personal computer.

Toward extracting scattering phase shift from integrated correlation functions III: coupled-channels
For coupled-channel systems, the trapped integrated correlation function difference converges to a weighted integral over the sum of the two channel phase shifts, independent of inelasticity.
