Abstract

The recent measurements of the reactions $p p \to p p π^{0}$ and $p n \to p p π^{-}$ by the ANKE collaboration at COSY are analyzed with the focus on the p-wave pion production amplitudes. These amplitudes are known to provide an important connection between $N N \to N N π$ and other low-energy few-nucleon reactions. The results of the recent partial wave analysis of the ANKE data are discussed and compared with the theoretical predictions.
