Description:
The Standard Model and General Relativity provide an excellent description of our present measurements in particle physics and gravitation. Yet we know that new physics is needed. Puzzles include tiny neutrino masses, baryogenesis (the matter-antimatter asymmetry in the Universe), dark energy and dark matter as well as the physics associated with primordial inflation.
The book develops the idea of an emergent Standard Model: that its gauge symmetries and particles might be ‘born’ in a topological like phase transition deep in the ultraviolet with the Standard Model parameters (the masses and couplings) linked to the stability of the vacuum. With emergence the gauge symmetries would ‘dissolve’ in the extreme ultraviolet instead of extra unification. Neutrinos would be their own antiparticles. The cosmological constant scale comes out naturally in this approach, similar in size to the value of light Majorana neutrino masses. There are also interesting constraints on dark matter scenarios.
Following an introduction to the Standard Model and the present status of our knowledge of fundamental interactions, the book discusses the key ideas of vacuum stability and emergent gauge symmetries. The phenomenology of an emergent Standard Model and its consequences for cosmology and early Universe physics are then explored. With a new generation of experiments both in particle and gravitational physics soon to begin plus expected advances in cosmology, the book serves both as an introduction and invitation to join new thinking in this physics with possible deep connections between the world of experiments and physics in the far ultraviolet.

Steven Bass is a Visiting Professor at the Jagiellonian University in Krakow. Previous awards have included as Research Fellow of Clare Hall in Cambridge UK, Alexander von Humboldt Research Fellow in Bonn, Germany and FWF Lise-Meitner Fellow in Innsbruck, Austria. He was awarded the Bragg Gold Medal of the Australian Institute of Physics for his Ph D in 1992 ‘Spin dependent effects in Quantum Chromodynamics’.His research interests have included the cosmological constant puzzle, emergent gauge symmetries in particle physics and cosmology, physics of the Higgs boson, positronium physics and aspects of Quantum Chromodynamics (especially the spin structure of the proton and η’ meson physics).Steven Bass has organized 3 Humboldt Kolleg conferences on particle physics and its interface to gravitational and quantum physics (2016-22) and (with M Klute and S Vitale) an Heraeus seminar on the interface of particle physics and gravitational waves (2025), each in Kitzbühel Austria. He has published a monograph on the Spin Structure of the Proton (WSPC, 2007) and has co-edited two volumes of Philosophical Transactions of the Royal Society A (2021 and 2023).
‘Steven Bass’ book on emergent symmetries makes a compelling case for the new paradigm of emergence as the guiding principle for understanding elementary particle physics and its mysteries and open problems. There is a need to understand and find the patterns that characterize the Standard Model of particle physics and provide clues to solutions to unsolved problems in particle physics and cosmology, where gravity merges with particle physics. Condensed matter physics is a treasure trove of emergent phenomena that often helps to understand structures such as renormalizable quantum field theories and their underlying symmetries. Enjoy reading this comprehensive introduction and gain a new perspective on particle physics, cosmology, and what nature might reveal to us beyond.’ – Professor Fred JegerlehnerDESY-Zeuthen and Humboldt Universität zu Berlin
‘This is a great book that challenges our thinking about extensions of the modern theory of elementary interactions, the Standard Model, and its interface with cosmology. The Standard Model, completed by the discovery of the Higgs boson at the LHC in 2012, is astonishingly successful in describing all so far observed phenomena in particle physics, except the tiny neutrino masses. Its underlying principle is gauge symmetry. The simplest dynamical system, considered by many as a toy model, self-interacting scalar field responsible for the Brout-Englert-Higgs mechanism as the origin of the Fermi scale is now promoted to a real thing. The Standard Model, combined with the picture of the thermal universe also explains the Big Bang Nucleosynthesis and what has happened in the universe after that. However, neutrino masses and the very early universe with its dark matter production and baryon-antibaryon asymmetry generation call for extending the Standard Model. The most common approach is to search, so far unsuccessfully, for new mass scales and for even more fundamental gauge symmetries, like for instance Grand Unification of all elementary forces. The author takes a radically different point of view. After a compact and perfectly presented review of the basics of the Standard Model, he shows that the gauge symmetry of the Standard Model can be an effective, ‘low energy’ pattern of elementary interactions, which dissolves at high energy in some topological phase transitions. Such an approach is predictive, avoids certain puzzles of the Standard Model and can address its limitations! The book is refreshing and definitely worth reading.’ – Professor Stefan PokorskiUniversity of Warsaw
