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
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.
