How Precisely can we Determine the $\piNN$ Coupling Constant from the Isovector GMO Sum Rule?

The isovector GMO sum rule for zero energy forward pion-nucleon scattering iscritically studied to obtain the charged pion-nucleon coupling constant usingthe precise negatively charged pion-proton and pion-deuteron scattering lengthsdeduced recently from pionic atom experiments. This direct determin...
