Mathematical Sciences at Plymouth will be hosting the CERN senior research fellow Maxwell Hansen next week, collaborating with Antonio Rago and Argia Rubeo.

He will also be presenting a seminar in the theoretical physics seminar:

Title: Multi-hadron observables from lattice QCD

Abstract:

The strong force is governed by a mathematical framework called quantum

chromodynamics (QCD). The building blocks of QCD are quarks and gluons,

and the interactions of these constituents leads to a rich variety of

observed phenomena. A particularly intriguing aspect of QCD physics is

the nature and behavior of resonances, short-lived states that decay via

the strong force. In this talk I will discuss progress in studying these

states, by calculating multi-hadron scattering observables. This by

achieved by combining field-theoretic ideas with large scale numerical

calculations based in lattice QCD. In particular, I will focus on the

idea of using the finite volume required for numerical calculations as a

tool, rather than an unwanted artifact, to extract dynamical observables

such as two- and three-hadron scattering amplitudes.
