The QCD spectrum: Challenges and prospects
From quarks and gluons, the emergence of hadrons is governed by the theory of strong interactions, quantum chromodynamics (QCD). However, its non-perturbative nature prevents us from determining the hadron spectrum algebraically. The way these basic constituents arrange into the matter we observe remains a mystery. Furthermore, some of these hadron interactions are very challenging from an experimental perspective, which has led to conflicting results in the past.
In this talk, I will explain the role that modern amplitude-analysis and first-principles techniques play in hadron physics. I will first highlight how first principles allow us to solve longstanding puzzles
like the determination of hadrons that go beyond the quark-model predictions. Then, I will review how Lattice QCD could enable us to decipher their structure and composition.
