Abstract
A unitary framework based on the Bakamjian-Thomas construction of relativistic quantum mechanics is used to describe two-pion scattering from threshold to 1400 MeV. The framework properly includes unitarity cuts for one-, two- and three-hadron states and provides an excellent description of the available data for pi pi phase shifts and inelasticities. The role and importance of three-hadron cuts are calculated and discussed.
