Three particles on the lattice
arXiv:1911.01253
Abstract
I give a review of existing frameworks, which are designed to analyse lattice data in the three-particle sector. A particular emphasis is laid on the foundations of the theory, where the separation of the short- and long-range effects plays a central role. It is shown that the use of the effective field theory approach enables one to carry out this separation in a natural and efficient way. In conclusion, a few examples of the analysis of lattice data are considered for illustration.
