Abstract
We present new momentum-space regularized nucleon-nucleon (NN) potentials up to fifth order in chiral effective field theory, whose adjustable parameters have been determined from experimental NN scattering data. The resulting N\(^4\)LO\(^+\) potential achieves the same precision as high-quality phenomenological forces while the new momentum-space regulator paves the way for the implementation of consistently regularized three-nucleon forces and current operators.
