The ηNN coupling constant -: art. no. 065205

We derive the light cone QCD sum rule for the eta NN coupling constant g (eta NN). The contribution from the excited states and the continuum is subtracted cleanly through the double Borel transform with respect to the two external momenta. p(1)(2),p(2)(2) = (p - q)(2). Our result is alpha (eta NN) = (0.3+/-0.15), which favors small values used in the literature.
