abstract = {We discuss the current status of chiral effective field
theory in the three-nucleon sector and present selected
results for nucleon–deuteron scattering observables based
on semilocal momentum-space-regularized chiral two-nucleon
potentials together with consistently regularized
three-nucleon forces up to third chiral order. Using a
Bayesian model for estimating truncation errors, the
obtained results are found to provide a good description of
the experimental data. We confirm our earlier findings that
a high-precision description of nucleon–deuteron
scattering data below pion production threshold will require
the theory to be pushed to fifth chiral order. This
conclusion is substantiated by an exploratory study of
selected short-range contributions to the three-nucleon
force at that order, which, as expected, are found to have
significant effects on polarization observables at
intermediate and high energies. We also outline the
challenges that will need to be addressed in order to push
the chiral expansion of three-nucleon scattering observables
to higher orders.},
