Research in the high energy group at the Racah Institute spans from theory to phenomenology. The research covers many of the central topics in the field. These include Physics beyond the Standard Model; research on quantum field theory and supersymmetry including supersymmetry breaking; String theory, including branes and extra dimensions; Scattering amplitudes, surprising new concepts and methods for gauge theories and gravity; Einstein's gravity, including the Effective Field Theory approach to General Relativity and in particular to the post-Newtonian limit of the gravitational two body problem; and Black holes.
Research in high energy phenomenology at the Racah Institute aims to address fundamental questions left unanswered by the Standard Model of particle physics: What are the dark matter particles of the Universe? Why does our world consist almost entirely of matter and not of anti-matter? Why is the mass of the weak force carriers so much smaller than the scale of gravity? These are several of many indications that there must be new physics beyond the Standard Model. The Large Hadron Collider (LHC), operating at record-breaking energies, together with a host of astro-particle observatories, will teach us much in this regard. Our research focuses on the phenomenology of such new particles and interactions, with particular emphasis on novel theoretical ideas and experimental signals at the LHC and other experiments. We study new ideas for the exploration of dark matter, proposing new theories of its particle identity, as well as novel experimental avenues to detect it on earth. Furthermore, we are extensively interested in non-standard theories of new physics and in the identification of exotic experimental signatures that have been overlooked, towards the goal of identifying the fundamental constituents of Nature.
