On the Coupling of the $\eta $ Meson to the Nucleon

Nuclear Theory 2009-10-30 v1

Abstract

The pseudoscalar and pseudovector ηN\eta N coupling constants are calculated from an effective vertex associated with the a0(980)πNa_0(980)\pi N triangle diagram. The predicted values are in agreement with the ones concluded from fitting η\eta photoproduction amplitudes. In this context we stress the importance of the properties of the scalar meson octet for η\eta meson physics.
