Particle Physics and Role of Fundamental Constants

Professor, Univ of Munich

The masses of the Leptons and Quarks are the central puzzles of the Standard Model of particle physics. The observed mass hierarchies indicate the role of dynamical symmetries, which enforce relations between the masses and the flavor mixing angles. CP violation emerges to be maximal. The mixing angles and the unitarity triangle are uniquely described in terms of mass eigenvalues. Thus far the agreement between experiment and theory is impressive.
