Unitarity of the infinite-volume three-particle scattering amplitude arising from a finite-volume formalism
Physical Review D
In a previous publication, two of us derived a relation between the scattering amplitude of three identical bosons, M_3, and a real function referred to as the divergence-free K matrix and denoted K_df,3. The result arose in the context of a relation between finite-volume energies and K_df,3, derived to all orders in the perturbative expansion of a generic low-energy effective field theory. In this work we set aside the role of the finite volume and focus on the infinite-volume relation betweendoi:10.1103/physrevd.100.054508 fatcat:ukddxtlw2zfajiszsk3e2afwge
