21 Hadron spectroscopy (Baryon resonances ) Research activities: establishing a link between experiment and theory

22 (i) neutrino dark energy We have shown that a simple coupled system of a variable vacuum term and a 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 significant portion of the history of the universe [R. Horvat, JCAP 0601 (2006)015]. (ii) holographic dark energy (iii) renormalization-group running cosmology Cosmology Large extra dimensions
