[PAST EVENT] Physics Colloquium - Monahan
January 28, 2016
4pm - 5pm
Abstract:
Protons and neutrons make up most of the mass of the visible Universe, but our knowledge of their internal structure is far from complete. Quantum chromodyamics (QCD), the theory of the strong force, provides the mathematical framework that connects protons and neutrons to their constituent quarks and gluons, but QCD cannot be solved analytically.
Instead, we must use lattice QCD, in which we discretise spacetime and study QCD numerically, usually on large supercomputers. I will introduce lattice QCD, discuss our need for a numerical approach to QCD, and highlight some of the many ways in which lattice QCD contributes to our understanding of particle and nuclear physics.
