Research summary

It is a mystery why there is no primordial antimatter in our observable Universe despite the fact that the known laws of physics predict an almost full symmetry between matter and antimatter. These would annihilate resulting in a current Universe made essentially of light (we should not be here!). At the same time about eighty four percent of matter is in a mysterious dark component with properties that no known elementary particles have. The key to the solution of these cosmological puzzles might reside in properties of the most elusive known particles: neutrinos. Neutrino oscillation experiments established that there are three neutrinos with tiny masses compared to all other massive fermions. Their origin is still a mystery maybe related to neutrinos being their own antiparticles. During my Newton International fellowship period, I would like explore new models of elementary particles describing neutrino masses and mixing able to provide a solution to the cosmological puzzles with predictions testable in future experiments.
