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.","authors_text":"Evgeny Epelbaum, Ulf-G.
