*Nuclear Forces From Chiral EFT: The Unfinished Business*

Ruprecht Machleidt
University of Idaho

In recent years, there has been substantial progress in the derivation
of nuclear forces from chiral effective field theory (EFT). Accurate
two-nucleon forces have been constructed at next-to-next-to-next-to-leading
order (N3LO) and applied (together with three-nucleon forces at N2LO) to
nuclear few- and many-body systems - with a fair deal of success. This
may suggest that the 80-year old nuclear force problem has finally been
cracked. Not so! Some pretty basic issues are still unresolved. In my
talk, I will focus on the two most pressing ones, namely, subleading
many-body forces and the proper renormalization of the two-nucleon potential.
