Query: High-precision nuclear forces from chiral EFT: State-of-the-art,
  challenges and outlook   We review a new generation of nuclear forces derived in chiral effective
field theory using the recently proposed semilocal regularization method. We
outline the conceptual foundations of nuclear chiral effective field theory,
discuss all steps needed to compute nuclear observables starting from the
effective chiral Lagrangian and consider selected applications in the two- and
few-nucleon sectors. We highlight key challenges in developing high-precision
tree-body forces, such as the need to maintain consistency between two- and
many-body interactions and constraints placed by the chiral and gauge
symmetries after regularization.
