Query: The role of the background in the extraction of resonance contributions
  from meson-baryon scattering   The separation of background and resonance contributions in pion-nucleon
scattering is an often discussed issue. We investigate to what extent the
background can be separated from the pole contribution. For illustration we use
results from an analytic model for the meson-baryon interaction derived from
meson exchange. We focus on the two distinct cases of an elastic and a highly
inelastic resonance, namely the Delta(1232) and the Delta*(1700). Our results
are also relevant for studies of dynamically generated resonances and attempts
to extract bare quantities from hadronic models to be compared to quark model
results.
