Dr. Arkaitz Rodas, Jefferson Laboratory, Newport News VA, Title: 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 unsolved. Furthermore, studying some of these hadron interactions is 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 these principles allow us to solve longstanding puzzles like the determination of hadrons that go beyond the quark-model predictions. Then, I will summarize how Lattice QCD could enable us to decipher fundamental questions about their formation.”
