Abstract:

In my talk, I review the use of the effective field theories in a finite volume for the analysis of lattice QCD data. In the beginning, I will sketch the derivation of the two- and three-body quantization condition. The extraction of the matrix elements of currents between multiparticle states will be also considered. The main focus of the review is on the inclusion of the long-range forces in the quantization condition that has attracted much interest in the recent years in the context of the lattice studies of the $T_{cc}^+(3875)$ as well as the low-energy NN scattering.
