Quarks, gluons and lattices

Friday April 7, 2017
4:00 pm

 Presenter:  Dr. Michael Creutz
Brookhaven National Laboratory
 Series:  Physics and Astronomy Colloquium
 Abstract:  Quantized Yang-Mills fields lie at the heart of our understanding of the strong nuclear force. To understand the theory at low energies, we must work in the strong coupling regime. The primary technique for this is the lattice. While basically an ultraviolet regulator, the lattice avoids the use of a perturbative expansion. I discuss the historical circumstances that drove us to this approach, which has had immense success, convincingly demonstrating quark confinement and obtaining crucial properties of the strong interactions from first principles.
