• Abstract:

  Neutrinos play a fundamental role in a number of important astrophysical processes and possibly in other unexplained phenomena. Neutrino interactions and masses contribute to explain the baryon asymmetry of the Universe in the so-called leptogenesis mechanisms. Neutrinos may also play a role in yet to explain phenomena as supernova explosions or pulsar kicks. On the other hand basic questions such as the Majorana or Dirac nature of neutrino masses are awaiting better ideas. One aims to investigate and contribute with new approaches to subjects as leptogenesis, neutrino oscillations in polarized media, and their relations with low energy neutrino mass and mixing spectrum.
