Amplitude Analysis for Mesons and Baryons: Tools and Technology

TL;DR

This paper discusses the analytic properties of resonant amplitudes in meson and baryon physics, emphasizing model-independent analysis methods and illustrating them with B and B_s decay processes.

Contribution

It introduces tools and techniques for model-independent amplitude analysis of resonances in meson and baryon decays.

Findings

Resonant amplitude properties are crucial for understanding hadron resonances.

Model-independent analysis provides robust insights into decay processes.

Application to B and B_s decays demonstrates the effectiveness of the methods.

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.
