Neutrino oscillation experiments involving neutrinos and antineutrinos coming from astrophysical and terrestrial sources have found compelling evidence that neutrinos have finite but small masses. Generating neutrino masses through the seesaw mechanism is among the most attractive ones to accommodate this observation. It explains the smallness of neutrino mass by supplying a suppression factor of the ratio of electroweak scale to a new physics scale. The most direct way of verifying the seesaw mechanism is, of course, to produce the heavy degrees of freedom in the models if they are light enough. The Large Hadron Collider (LHC) at CERN with its unprecedented high energy and luminosity is the best place to carry out such a test. In this talk I will show the possibility to test type I seesaw mechanism for neutrino masses with B-L gauge symmetry and a radiative seesaw mechanism with a dark matter candidate at the CERN Large Hadron Collider based on our recent studies. The flavor combinations of the charged leptons from the decay of heavy Majorana neutrino are related to the light neutrino mass and mixing parameters and thus may reveal the hierarchical pattern of the neutrino masses. I will discuss these issues and show the most optimistic cases where one could hope to test these neutrino mass generation mechanisms, dark matter properties and reveal the existence of the B-L symmetry. |
