Neutrinos as a probe of physics beyond the standard model Meloni, Davide Neutrinos Oscillations CP violation Mass Presented at the final meeting of the European Network "Physics at Colliders", Montpellier, France, september 26-27, 2004. Neutrino physics plays a very important role in understanding several aspects of fundamental physics. In this short review, we revise three different aspects connected to them. Neutrino oscillations at low energy (up to few GeV) offer the possibility to study possible leptonic CP violation whereas at ultra-high energy (Eν > 103 TeV) they could enable to check scenarios of Physics Beyond the Standard Model involving extra-dimensions. On the other hand, e+e− colliders can help in detecting new heavy Majorana neutrinos suggested by Grand Unified Theories with masses of O(102 GeV). 2014-07-08T10:52:05Z 2014-07-08T10:52:05Z 2004 info:eu-repo/semantics/article Meloni, D.
