The Problem of Mass and Mass Generation
Harald Fritzsch
Abstract
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.
