Peripheral nucleon-nucleon scattering at fifth order of chiral perturbation theory

Year: 2015

Type: article

Abstract: The authors report results for $N\phantom{\rule{0}{0ex}}N$ scattering in higher partial waves based on chiral perturbation theory to 5th order in the expansion. As the first such calculation to this order, the work sets a new standard for the derivation of the $N\phantom{\rule{0}{0ex}}N$ interaction in chiral perturbation theory. The results are not very sensitive to the single cut-off parameter.
