摘要：
We study models with radiative neutrino mass generation and explore the relation between the neutrino masses and dark energy. In these models, the pseudo-Nambu-Goldstone bosons (pNGBs) arise at two-loop level via the Majorana neutrino masses. In particular, we demonstrate that the potential energy of the pNGB could be the dark energy potential and the observed value of the equation of state parameter of the universe, i.e., w similar or equal to-1, can be realized.
