How precisely can we determine the pion-nucleon coupling constant from the isovector GMO sum rule?
B. Loiseau, T. E. O. Ericson, A. W. Thomas
The isovector GMO sum rule for zero energy forward pion-nucleon scattering is critically studied to obtain the charged pion-nucleon coupling constant using the precise negatively c…

Precise strength of th piNN coupling constant
T. E. O. Ericson, B. Loiseau, J. Rahm +3
We report here a preliminary value for the piNN coupling constant deduced from the GMO sumrule for forward piN scattering. As in our previous determination from np backward differe…

Systematic effects in the determination of the piNN Coupling from pbar p -> nbar n differential cross section
T. E. O. Ericson, B. Loiseau
We show that the coupling constant extracted model-independently from charge exchange is subject to a systematic correction, and, more importantly, that the strong…
