Prof. Hübsch’s research interests are focused on various theoretical and mathematical aspects of fundamental physics, including high energy particle physics, gauge theories, supersymmetry, string theory and its M- and F-theory extensions, but also include some related cosmology. His research addresses both the study of the mathematical methods and techniques used in these subjects, and also their concrete application towards a more realistic Theory of More than Everything.
Most recently, he has worked on developing the representation theory of supersymmetry, the goal of which is to have a complete classification of so-called off-shell supermultiplets and their possible interactions. Supersymmetry is the only known universal mechanism that stabilizes the vacuum, and it necessarily bundles particles into supermultiplets. The knowledge of off-shell (as opposed to on-shell) such supermultiplets is necessary for a consistent quantum field theory, and is sorely incomplete to date. In turn, direct experimental evidence for so-called super-partners of the known particles is expected to be seen in soon experiments to be run at international centers such as CERN, in Europe. Most of this work has been accomplished in collaborations with Profs. C.F. Doran (University of Alberta, Canada), M.G. Faux (SUNY, Oneonta), S.J. Gates, Jr., (University of Maryland, College Park), K.M. Iga (Pepperdine University, Malibu) and G.D. Landweber (Bard College, Annandale-on-Hudson).
Besides, supersymmetry representation theory, Prof. Hübsch is also working on studying string- and M-theory inspired and hopefully realistic cosmological models, and their particular features. On one hand, this includes so-called Bran-World cosmological models where supersymmetry breaking turns out to be related to the small cosmological constant and to the exponentially large hierarchy between the Planck energy scale and the energy scale of electro-weak interactions and the observed masses of elementary particles observed currently. On the other, this includes so-called Calabi-Yau superstring compactifications.
