Continuous and discrete effective nuclear physics.

We report on the recent developments of chiral effective field theory for nuclear physics based on Weinberg's power counting. Continuum calculations for deuteron photodisintegration, pion production in neutron-proton fusion and baryon-baryon interactions with strangeness S = -3 and S = -4 are discussed. The lattice formulation of the nuclear forces offers the possibility to study the nuclear many-problem. First results of this approach and some estimates for future simulations are shown.
