Amplitude Analysis for Mesons and Baryons: Tools and Technology

Abstract

In these proceedings some facts about resonances are discussed focussing on the analytic properties of resonant amplitudes with special emphasis on model independent analyses. As an illustrative example of the latter point the decays B and B_s to J/psi pi pi are discussed in some detail.
