High Energy Physics

Supersymmetric gauge theories, strong coupling phenomena, dynamical Casimir effect, black hole radiation

• 1972-1982 and 1990-1995: QCD, Strong interaction Physics, Heavy Quark Physics, axions;
• 1982-1990 and since 1996: All aspects of supersymmetric theories at strong coupling;
• Since 2003: Supersymmetric solitons, sigma models (including applications in Condensed Matter).

I am interested in precision tests of the Standard Model in a variety of setting, from particle colliders to low-energy precision probes. A significant part of my research is devoted to the dark matter problem and new ideas that could help to discern its properties.

My research is in the area of particle physics and cosmology. The main topics on which I work are: big bang nucleosynthesis, which is an explanation of the origin of the light element isotopes through 7Li; particle dark matter; big bang baryogenesis, which is an explanation of the matter-antimatter asymmetry observed in nature; and inflation which is a theory constructed to resolve many outstanding problems in standard cosmology.
