My research activity is mostly in supersymmetric extensions of the Standard Model of Electroweak and Strong Interactions. I work in the general areas of SUSY phenomenology, astroparticle physics and cosmology.
Currently I am involved in several aspects of SUSY physics:
- Unification of gauge coupling, Yukawa coupling and SUSY masses in the context of grand unified models like SO(10), and those motivated by supergravity, superstrings, M-theory and extra dimensions;
- Neutralino Dark Matter: properties and prospects of detection of the lightest neutralino as the lightest supersymmetric particle (LSP) in colliders and a dark matter candidate in underground searches;
- Axino - New Dark Matter Candidate: we have recently introduced the axino (fermionic partner of the axion) as a novel candiate for cold dark matter. Axino cosmology is in many respects very different from the usual one;
- Gravitino - Old Dark Matter Candidate:
historically first DM
candidate, the gravitino (fermionic partner of the graviton) has
generated a lot of interest because of its potential problems.
Gravitino's viability critically depends on improving measurements of
cosmological and astrophysical parameters;
- Flavour and CP Problems including specific models and mechanisms for solving the problems, and ways of falsifying them in experiment. SUSY contributions to these processes.
