Michael Creutz (Brookhaven):
Quarks, Gluons, and Lattices
Abstract:
Lattice gauge theory provides a
mathematical formalism for first principles calculations of the interactions
of quarks and gluons, the basic constituents of particles feeling the nuclear
force. In this approach the paths of quarks through spacetime are approximated
by discrete hops on a lattice. The lattice itself is a mathematical trick,
and at the end of the calculation the underlying spacing is extrapolated to zero.
However, with the lattice in place the system can be studied via computer simulations.
In this talk I review the history that drove particle theorists to this technique
and become major supercomputer users.
