Howard Georgi has ongoing research programs in several areas of theoretical particle physics. The common elements in these areas are symmetries and quantum field theory. Georgi pioneered the subject of Grand Unified Theories, both without (with Sheldon Glashow) and with supersymmetry (with Savas Dimopoulos), invented the modern QCD quark model (with Glashow and Alvaro De Rujula), the chiral quark model (with former student Aneesh Manohar), and the Heavy Quark Effective Theory.
The most important issue in particle physics today is the interpretation of the discoveries at the LHC. Is the Higgs-like particle that has been seen simply a fundamental scalar, or does it have more structure or as-yet unseen relatives? Georgi (who with former student David Kaplan showed how one could build composite Higgs bosons) studies the possibility of strong coupling models for the Higgs. Recently, Georgi has been exploring the properties of theories in which a scale-invariant sector of the world is weakly coupled to the standard model. In the scale invariant sector, energy and momentum is not bundled in particles, so Georgi dubbed this strange situation "unparticle physics" (DOI: 10.1103/PhysRevLett.101.131603). He is currently studying a class of models with discrete scale invariance. These have fascinating mathematical properties that he hopes may have applications beyond quantum field theory.
Georgi also studies QCD, the formalism of effective field theories, the strong CP problem, and the flavor puzzle, and explores new ways of understanding the complicated events that experimenters see in high-energy collisions.
In addition, he is interested in increasing the participation of women and minorities in science and is on a number of local and national committees that attempt to address this important issue.
