Efimov physics in finite volume

Simon Kreuzer (Bonn)

Three particles with large scattering length display a universal spectrum of three-body bound states called "Efimov trimers". I show the modification of the Efimov trimers of three identical bosons in a finite cubic box and compute the dependence of their energies on the box size using effective field theory. The renormalization of the effective field theory in the finite volume is explicitly verified. The effects of partial wave mixing and the behavior of shallow trimers near the dimer energy are investigated. This program has recently been extended to the three-nucleon system. I present results for the triton in a finite volume including a study of the triton spectrum at unphysical pion masses.
