Understanding the volume dependence of the triton binding energy is an important step towards lattice simulations of light nuclei.
- We calculate the triton binding energy in a finite cubic box with periodic boundary conditions to leading order in the pionless effective field theory.
- Higher order corrections are estimated and the proper renormalization of our results is verified explicitly.
- We present results for the physical triton as well as for the pion-mass dependence of the triton spectrum near the ``critical'' pion mass, Mpi_c ~ 197 MeV, where chiral effective field theory suggests that the nucleon-nucleon scattering lengths in the singlet- and triplet-channels diverge simultaneously.
