# SLAC Theory Group

The SLAC Theory Group is the hub of theoretical particle physics research at the SLAC National Accelerator Laboratory at Stanford University. It is a subdivision of the Elementary Particle Physics (EPP) Division at SLAC.

## Research

The group has a diverse research program, specializing in areas of quantum field theory, beyond the standard model physics, dark matter, neutrinos, and collider phenomenology.

## Members

The group is currently led by 9 faculty members, and has a dozen postdoctoral researchers and students at any given time.
Notable physicists who were students or postdoctoral researchers in the SLAC Theory Group include Nima Arkani-Hamed, Thomas Appelquist, Mirjam Cvetic, Michael Dine, John Ellis, Rouven Essig, Edward Farhi, Steven Frautschi, Joshua Frieman, Roscoe Giles, Yuval Grossman, Jack F. Gunion, Alan Guth, Howard Haber, Claude Itzykson, Robert Jaffe, David E. Kaplan, Igor Klebanov, Peter Lepage, Christopher Llewellyn Smith, Kirill Melnikov, Stephen Parke, Maxim Perelstein, Joel Primack, Joseph Polchinski, Davison Soper, Henry Tye, Mark Wise, and Tung-Mow Yan.
Past and present members of the SLAC Theory Group have received a total of at least 3 Breakthrough in Fundamental Physics Prizes ($3 million USD prize), 10 Sakurai Prizes ($10,000 USD), 5 Dirac Medals ($5,000 USD), 4 New Horizons in Physics Prizes ($100,000 USD), and 2 Gribov Medals ($5,000 USD).
