The Lepton-Quark Mass Spectrum—A Guide to the Physics Beyond the Standard Model

The standard model of quarks, leptons and their gauge interactions gives a complete description of all phenomena observed in particle, nuclear and atomic physics. Nevertheless it is a model based on about twenty free parameters and can, for this reason, hardly be regarded as the final theory of the basic constituents and forces of nature. A closer inspection of these parameters, however, reveals that the majority of these parameters (13) refer to the lepton—quark mass spectrum and to the associated weak interaction mixing parameters. Thus any further insight into the dynamics which is responsible for the spectrum of leptons and quarks would at the same time be a step beyond the standard model and an important step towards the construction of a theory which would allow theoreticians eventually to calculate all parameters of the standard model in terms of one free mass or scale parameter, e.g. the Planck mass.
