3-hadron problem from lattice QCD — •Maxim Mai — University Bonn, Bonn, Germany

The enigma of the spectrum of the strongly interacting particles (hadrons) includes many puzzles. What is the general form of the spectrum of excited states of hadrons? Why do some resonances resemble simple Breit-Wigner form and others do not? Can we say something about the nature of individual states?

The challenge in answering these questions arises from the very structure of the Quantum Chromodynamics (QCD) -- the quantum field theory of strong interaction. In that, lattice gauge theory is the only tool available to us to tackle the non-perturbative dynamics of QCD which already led to many important insights.

Currently the frontier of hadron spectroscopy from first principles is entering a new phase, addressing dynamics of resonant multi-hadron states. This has become possible by many groundbreaking advances of theoretical and computational techniques, which I will describe in my talk. The remaining part of the talk will be devoted to the recent results on states of high relevance, bridging the gap to experimental results.
