For meson-baryon pairs tied to the N*(1535), off-shell ambiguities change correlation functions by only 2-3% in chiral models, and can be partly absorbed by adjusting the source size.

abstract
We study the S-wave interaction of mesons with baryons in the strangeness S=0 sector in a coupled channel unitary approach. The basic dynamics is drawn from the lowest order meson baryon chiral Lagrangians. Small modifications inspired by models with explicit vector meson exchange in the t-channel are also considered. In addition the pi pi N channel is included and shown to have an important repercussion in the results, particularly in the isospin 3/2 sector.

Off-shell ambiguities in correlation functions: strategies to minimize them
For meson-baryon pairs tied to the N*(1535), off-shell ambiguities change correlation functions by only 2-3% in chiral models, and can be partly absorbed by adjusting the source size.
