Hadron spectroscopy (Baryon resonances) Researchactivities: establishing a link between experiment and theory
Cosmology (i) neutrino dark energy We have shown that a simple coupled system of a variable vacuum term anda gas of relic neutrinos may account not only for a right amount of dark energy at present, but also for a near coincidence between the matter and dark-energy densities to hold over a significantportion of the history of the universe [R. Horvat, JCAP0601(2006)015]. (ii) holographic dark energy (iii) renormalization-group running cosmology Large extra dimensions
