Influence of the magnetic interactions on the mass spectrum of elementary particles

Different approaches to the problem of mass quantization are discussed. The Barut ideas of crucial influence of magnetic forces for explaining the properties of the strong interaction are considered in details. It is shown that this approach gives the possibility to understand the enormous number of elementary particles (about 400) as the excited states of stable fundamental particles (e, p, v), bounded by magnetic interactions. © Published under licence by IOP Publishing Ltd.
