abstract
We study the two-pion exchange potential at next-to-next-to-leading order in chiral effective field theory. We propose a new cut-off scheme for the pion loop integrals based on spectral function regularization. We show that this method allows for a consistent implementation of constraints from pion-nucleon scattering. It leads to a much improved description of the partial waves with angular momentum l \geq 2 as compared to the calculation utilizing dimensional regularization.

Scrutiny of the new class of three-nucleon forces
