Title: Unfolding the Second Riemann sheet with Pade Approximants: hunting resonance poles

Abstract

Based on Pade Theory, a new procedure for extracting the pole mass and width of resonances is proposed. The method is systematic and provides a model-independent treatment for the prediction and the errors of the approximation.
