The Problem of Mass and Mass Generation
Fritzsch, Harald
Original · EN
The mass problem in particle physics for other fields is discussed. While the problem of the nuclear masses has been resolved within the QCD framework, 3 parameters of the ``Standard Model'' are related to the fermion sector. The origin of the ferion masses remains unresolved. We discuss attempts to explain the observed hierarchical features of the mass spectrum by a symmetry. relating the mass eigenvalues to the flavor mixing angles.
