Title: Model-independent extraction of ππ and πN resonances from forward 
dispersion relations

Abstract:
A precise description of low-energy ππ and πN interactions is essential 
for many problems in hadronic physics. For the ππ system, we present new 
global fits that satisfy dispersive constraints
within uncertainties up to 1.6 GeV, while describing all available 
experimental data up to 1.8 GeV. Using continued-fraction expansions, we 
extract resonance pole parameters in a model-independent way from 
forward dispersion relations.
For πN scattering, following a careful revision of the database, we 
determine resonance parameters from forward dispersion relations using 
exclusively total cross-section data together with the optical theorem.

Best wishes,

Adam, Joe, and Pia
