Theoretical physics, elementary particles, supersymmetric theories.
Among the most relevant open questions in particle physics are the ones related to the origin of mass and to the existence of matter in the Universe. The answer to the first question relies on the mechanism of electroweak symmetry breaking, which can be tested through the corresponding Higgs physics at high energy collider facilities. The answer to the second question is more difficult, since the understanding of the origin of ordinary matter, the building blocks of atoms, and of dark matter, visible only via its gravitational interactions, demands new physics, beyond the current Standard Model description. One ambitious goal would be to find a scenario that led to an answer to all these questions in a natural way. Supersymmetric extensions of the standard model seem to provide the best framework to achieve such a goal, while allowing the possibility of a unified description of all particle interactions. For these reasons, my research activities focus on such supersymmetric extensions, putting emphasis on Higgs physics and on the possible experimental tests of these theories. Moreover, I investigate the possibility of generating all matter by physics at low energies, that may be testable at current experiments, or at those planned in the near future. One of the findings of my work is that this possibility may be realized in minimal supersymmetric extensions of the Standard Model, if some specific conditions are fulfilled. These conditions will be tested at the Tevatron collider, which is operating at the Fermilab Laboratory in the Chicago area, as well as the LHC collider at CERN, which will start operation by the end of the year 2007.
