We also consider briefly exotics like supersymmetry and extra dimensions in relation to the mass scale problem, including some mathematical arguments (e.g. We extend some plausible arguments for other scales, as binding or self-energy effects of the microscopic forces, plus some speculative uses, here and there, of gravitation. Indeed, some scales of masses will cover also masses of composite particles or mass differences. Another natural mass scale is Λ = Λ QCD coming arbitrarily at quantizing a classically conformal SU(3) c theory. We argue for some rather well defined mass scales, like the electron mass we elaborate on the assumption that there is a minimum mass associated to any electric charge. Each chapter ends with a set of problems for which outline solutions are provided.We make an attempt to describe the spectrum of masses of elementary particles, as it comes out empirically in six distinct scales. Appendices deal with other more specialized topics. A knowledge of basic quantum mechanics and special relativity is assumed. This second edition contains several additional topics: muon-catalysed fusion, the nuclear and neutrino physics of supernovae, neutrino mass and neutrino oscillations, and the biological effects of radiation. The book also includes chapters on nuclear fission, its application in nuclear power reactors, the role of nuclear physics in energy production and nucleosynthesis in stars. The book opens by setting nuclear physics in the context of elementary particle physics and then shows how simple models can provide an understanding of the properties of nuclei, both in their ground states and excited states, and also of the nature of nuclear reactions. This clear and concise introduction to nuclear physics provides an excellent basis for a core undergraduate course in this area. Description Product filter button Description
