| Publication Abstract: | The quantization condition for two-particle systems with arbitrary number of two-body open coupled channels, spin and masses in a finite cubic volume with either periodic or twisted boundary conditions is presented. The condition presented is in agreement with all previous studies of two-body systems in a finite volume. The result is relativistic, holds for all momenta below the three- and four-particle thresholds, and is exact up to exponential volume corrections that are governed by $L/r$, where $L$ is the spatial extent of the volume and $r$ is the range of the interactions between the particles. For hadronic systems the range of the interaction is set by the inverse of the pion mass, $m_\pi$, and as a result the formalism presented is suitable for $m_\pi L\gg1$. Implications of the formalism for the studies of multichannel baryon-baryon systems are discussed. |
