| dc.description | We point out subtleties in the previous sum rule calculations of the $πNN$ coupling associated with using either the PV or the PS coupling schemes in modeling the phenomenological side. We propose a sum rule which is independent of the coupling schemes used and has less uncertainty in the OPE. The obtained value is $g_{πN}=9.76 \pm 2.04$ where the uncertainty mainly comes from the quark-gluon mixed condensate. | |
