Foil 19 Case Study I) Topics -- Computation of Quantum Chromodynamics (QCD)

From Master set for Overview of Case Studies of Computational Science CPSP713 Master for Overview -- Autumn Semester 1994. by Geoffrey C. Fox * See also color IMAGE

T: Parallel Computation of both Sites and Measurements in Lattice Gauge Theories
A: Current Status of Computation of particle masses
  • Simulation agrees (surprisingly) well with experimental measurements
  • Monte Carlo uses a lot of supercomputer time as accuracy proportional to square root of computer time used
C: Adding Fermions (quarks) to a theory of Gluons (The "carrier" of strong interaction force)
  • Makes computation much lengthier but doesn't change (some) results much
  • Needed in any true theory of Nature
T: Hybrid Monte Carlo
  • Combination of deterministic (equation of motion) and Monte Carlo Methods
