*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.
