| Abstract |
The rich phenomenology of the strong nuclear force is described by an elegant
mathematical framework called quantum chromodynamics (QCD). The building blocks of
QCD are quarks and gluons and it is expected that studying these constituents and
their interactions should lead to quantitative predictions of strong force behavior,
from the basic properties of nuclei to the production mechanisms of heavy elements
in stars. 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 combining field theory ideas with
large scale computer calculations. I will describe the path toward precision
calculations of resonance properties—extracting scattering and transition amplitudes
and resonance form factors, for varying quark masses—in a model-independent approach
called lattice QCD.
