Neutral Kaons


Book Description

The neutral K meson or neutral kaon, K0, and its antiparticle, K(bar)0, form a remarkable quantum-mechanical two-state system that has played an important role in the history of elementary particle physics. Indeed, ever since the discovery of K0 half a century ago, neutral kaons have been a rich source of unique and facinating phenomena associated with their production, decay and propagation in both vacuum and matter. This overview conveys the unique beauty of a quantum-mechanical system that contains so many of the aspects of modern physics. WICHTIGE INFO: Satzanweisung!!! bitte setzen Sie bei K0 das Zeichen "0" als hochgestellte Null. K(bar) ersetzen Sie bitte, indem Sie uber das K einen Querstrich setzen und das "(bar)" dann bitte loschen. Danke, jlenz(Tel. 307)

Quantum Entanglement in High Energy Physics


Book Description

This book is devoted to research topics in quantum entanglement at the energy frontier of particle and nuclear physics, and important interdisciplinary collaborations with colleagues from fields outside of physics. A non-exhaustive list of examples of the latter can include mathematics, computer science, social sciences, philosophy, and how physics can interact with them in a way that supports successful outcomes. These are exciting times in the field of quantum information science, with new research results and their applications in society exhibiting themselves rather frequently. But what is even more exciting is that the frequency of these new results and their applications increases with a rapidity that will motivate new methods, new theories, new experiments, and new collaborations outside of the field that future researchers will find quite challenging.







Elementary Particles and Their Interactions


Book Description

The Standard Model of elementary particle physics was tentatively outlined in the early 1970s. The concepts of quarks, leptons, neutrinos, gauge symmetries, chiral interactions, Higgs boson, strong force, weak force, and electromagnetism were all put together to form a unifying theory of elementary particles. Furthermore, the model was developed within the context of relativistic quantum field theory, making it compatible with all of the laws of Einstein's Special Relativity. The successes of the Standard Model over the years have been tremendous and enduring, leading up to the recent discovery and continuing study of the Higgs boson. This book is a comprehensive and technical introduction to Standard Model physics. Martin and Wells provide readers who have no prior knowledge of quantum field theory or particle physics a firm foundation into the fundamentals of both. The emphasis is on obtaining practical knowledge of how to calculate cross-sections and decay rates. There is no better way to understand the necessary abstract knowledge and solidify its meaning than to learn how to apply it to the computation of observables that can be measured in a laboratory. Beginning graduate students, both experimental and theoretical, and advanced undergraduate students interested in particle physics, will find this to be an ideal one-semester textbook to begin their technical learning of elementary particle physics.

Signatures of the Artist


Book Description

How does the scientific enterprise really work to illuminate the origins of life and the universe itself? The quest to understand our universe, how it may have originated and evolved, and especially the conditions that allow it to support the existence of life forms, has been a central theme in religion for millennia and in science for centuries. In the past half-century, in particular, enormous progress in particle and nuclear physics and cosmology has clarified the essential role of imperfections - deviations from perfect symmetry or homogeneity or predictability - in establishing conditions that allow for structure in the universe that can support the development of life. Many of these deviations are tiny and seem mysteriously fine-tuned to allow for life. The goal of this book is to review the recent and ongoing scientific research exploring these imperfections, in a broad-ranging, non-mathematical approach with an emphasis on the intricate tapestry of elegant experiments that bear on the conditions for habitability in our universe. This book makes clear what we know and how we know it, as distinct from what we speculate and how we might test it. At the same time, it attempts to convey a sense of wonderment at the tuning of these imperfections and of the rapid rate at which the boundary between knowledge and speculation is currently shifting.




Kaon Physics


Book Description

In 1947, the first of what have come to be known as "strange particles" were detected. As the number and variety of these particles proliferated, physicists began to try to make sense of them. Some seemed to have masses about 900 times that of the electron, and existed in both charged and neutral varieties. These particles are now called kaons (or K mesons), and they have become the subject of some of the most exciting research in particle physics. Kaon Physics at the Turn of the Millennium presents cutting-edge papers by leading theorists and experimentalists that synthesize the current state of the field and suggest promising new directions for the future study of kaons. Topics covered include the history of kaon physics, direct CP violation in kaon decays, time reversal violation, CPT studies, theoretical aspects of kaon physics, rare kaon decays, hyperon physics, charm: CP violation and mixing, the physics of B mesons, and future opportunities for kaon physics in the twenty-first century.
