Group theoretical aspects of neutrino mixing in Quantum Field Theory


By resorting to recent results on the Quantum Field Theory of mixed particles, we discuss some aspects of three flavor neutrino mixing. Particular emphasis is given to the related algebraic structures and their deformation in the presence of CP violation. A novel geometric phase related to CP violation is introduced.Comment: 10 pages, 2 figures.
