Systematic effects in the determination of the $\pi$NN Coupling from $\overline{p}p \to \overline{n}n$ differential cross section
We show that the $\pi NN$ coupling constant extracted model-independently from $\bar pp$ charge exchange is subject to a systematic correction, and, more importantly, that the strong absorption in the critical region prevents a determination of the coupling constant to high precision using this proc...
