Abstract

摘要

Three-body channels play a relevant and sometimes dominant role at the energies of the resonance region. With dispersion relations a manifestly three-body unitary amplitude is derived. It could be used for data analysis of experiments like BES, COMPASS, or GlueX in the future. 

In view of upcoming lattice QCD calculations concerning three-body systems, unitarity identifies the imaginary parts of the amplitude where all particles are on-shell. Such states induce the leading power-law finite-volume effects that need to be known to extrapolate to the infinite volume. This extrapolation is demonstrated for spinless particles and one spinless isobar.
