Key Competences/Facilities

The six theoretical physicists in the Department of High Energy Physics are actively working on quantum chromodynamics, phenomenology of the SM, supersymmetry, and gravity duals as applied to strong interactions, as well as lattice gauge theory applied to the subject of this proposal. For the latter, we have computer clusters that are useful for medium-scale simulations, and a software suite based on the public MILC code adapted to the theories at hand.

Previous Training Programs and Research

We were among the first to apply lattice methods to higher-representation gauge theories, three years ago, when we applied the Schrodinger Functional method to look for an infrared fixed point. Since then we have been been diversifying our methods within the toolbox offered by lattice gauge theory. We have already graduated one M.Sc. student in the course of this research. Another M.Sc. student and a Ph.D. student are currently doing thesis work in this area. In all, 18 graduate students and three postdoctoral fellows are currently working in theoretical physics in the department.
