This book focuses on the most pressing unsolved problem in elementary particle physics – the mass generation of particles. It contains physics that is not included in the Standard Model as it is now formulated but at the same time is in conformity with its major results (i.e. isotopic spins and interactions). It differs from the Standard Model in the treatment of masses and pseudoscalar mesons, and in the role assigned to the coupling constant, α. Presented in a careful and phenomenological way, the material can easily be followed by all physicists, both experimental and theoretical, and also by interested workers in other fields.
