DESCRIPTION:\n    We will review the general phenomenology of neutrinoless
  double beta decay in seesaw models. In particular\, we focus on the depen
 dence of the decay rate on the mass of the extra states introduced to gene
 rate the light neutrino masses. The neutrino mass generation mechanism ind
 uces correlations among the different contribution to the decay rate which
  should be considered. We will study whether the contribution from the ext
 ra states can dominate over the light neutrino one. This may occur if the 
 ``heavy" spectrum is hierarchical with some of the extra states below ~100
  MeV and others above this scale. In principle\, a dominant heavy neutrino
  contribution is also possible at tree level for a different spectrum if t
 he light neutrino contribution partially cancels out. In the second part o
 f the talk we focus on this case paying special attention to the one-loop 
 corrections to light neutrino masses\, their contribution to the process a
 nd correlation with the heavy sector.\n\nhttps://indico.ific.uv.es/event/2
