"Most of the data that is relevant for particle physics came from collider experiments. The task of particle physicists is to identify the patterns in this raw data, and to organize them in such a way that the principles that explain this variety emerge. The currently accepted theory of organization in particle physics is called the Standard Model (SM), which describes three of the four known fundamental forces and establishes principles of symmetry amongst particles. This book describes the SM as it is understood today, providing readers with a deep understanding of the symmetry principles at play in constructing models of particle physics. It is designed to be used as a textbook, accompanying a one semester course for graduate students. While generally presented as an optional elective, graduate-level courses on particle physics are common to most universities that offer a PhD in Physics. While there are variety of textbook offerings in the space, including our own Elementary Particle Physics in a Nutshell and The Standard Model in a Nutshell, this book is unique in its systematic and pedagogical approach, as well as for its inclusion of cosmological tests, which current texts lack. It also has a unique focus on model-building. Many of the other books on this topic attempt to cover a mix of QFT and the SM. This text focuses squarely on the Standard Model and does not attempt to concurrently teach QFT. Rather, it assumes some prior knowledge (while not requiring mastery of the subject). Lastly, the book will offer a greater number of homework-level practice problems than its counterparts"-- "An authoritative, hands-on introduction to the foundational theory and experimental tests of particle physicsThe Standard Model is an elegant and extremely successful theory that formulates the laws of fundamental interactions among elementary particles. This incisive textbook introduces students to the physics of the Standard Model while providing an essential overview of modern particle physics, with a unique emphasis on symmetry principles as the starting point for constructing models. The Standard Model equips students with an in-depth understanding of this impressively predictive theory and an appreciation of its beauty, and prepares them to interpret future experimental results.Describes symmetry principles of growing complexity, including Abelian symmetries and their application in QED, the theory of electromagnetic interactions, non-Abelian symmetries and their application in QCD, the theory of strong interactions, and spontaneously broken symmetries and their application in the theory of weak interactionsDerives the Lagrangian that implements these symmetry principles and extracts the phenomenology that follows from it, such as elementary particles and accidental symmetriesExplains how the Standard Model has been experimentally tested, emphasizing electroweak precision measurements, flavor-changing neutral current processes, neutrino oscillations, and cosmologyDemonstrates how to extend the model to address experimental and observational puzzles, such as neutrino masses, dark matter, and the baryon asymmetry of the universeFeatures a wealth of problems drawing from the latest researchIdeal for a one-semester graduate course and an invaluable resource for practitionersOnline solutions manual (available only to instructors)"--

A concise introduction to the cutting-edge science of particle physicsThe standard model of particle physics describes our current understanding of nature's fundamental particles and their interactions, yet gaps remain. For example, it does not include a quantum theory of gravity, nor does it explain the existence of dark matter. Once complete, however, the standard model could provide a unified description of the very building blocks of the universe. Researchers have been chasing this dream for decades, and many wonder whether such a dream can ever be made a reality.Can the Laws of Physics Be Unified? is a short introduction to this exciting frontier of physics. The book is accessibly written for students and researchers across the sciences, and for scientifically minded general readers. Paul Langacker begins with an overview of the key breakthroughs that have shaped the standard model, and then describes the fundamental particles, their interactions, and their role in cosmology. He goes on to explain field theory, internal symmetries, Yang-Mills theories, strong and electroweak interactions, the Higgs boson discovery, and neutrino physics. Langacker then looks at the questions that are still unanswered: What is the nature of the mysterious dark matter and dark energy that make up roughly 95 percent of the universe? Why is there more matter than antimatter? How can we reconcile quantum mechanics and general relativity?Can the Laws of Physics Be Unified? describes the promising theoretical ideas and new experiments that could provide answers and weighs our prospects for establishing a truly unified theory of the smallest constituents of nature and their interactions.

This book gives a detailed account of the Standard Model of particle physics, focussing on the techniques by which the model can produce information about real observed phenomena. It opens with a pedagogic account of the theory of the Standard Model. Introductions to the essential calculational techniques are included. The major part of the text is concerned with the use of the Standard Model in the calculation of physical properties of particles. Rigorous and reliable methods (radiative corrections and nonperturbative techniques based on symmetries and anomalies) are emphasized, but other useful models (such as the quark and Skyrme models) are also described. The strong and electroweak interactions are not treated as independent threads but rather are woven together into a unified phenomenological fabric. Many exercises and diagrams are included.

The Standard Model is the most comprehensive physical theory ever developed. This textbook conveys the basic elements of the Standard Model using elementary concepts, without the theoretical rigor found in most other texts on this subject. It contains examples of basic experiments, allowing readers to see how measurements and theory interplay in the development of physics. The author examines leptons, hadrons and quarks, before presenting the dynamics and the surprising properties of the charges of the different forces. The textbook concludes with a brief discussion on the discoveries of physics beyond the Standard Model, and its connections with cosmology. Quantitative examples are given, and the reader is guided through the necessary calculations. Each chapter ends in the exercises, and solutions to some problems are included in the book. Complete solutions are available to instructors at www.cambridge.org/9781107406094.

This is a first-hand account of one of the most creative and exciting periods of discovery in the history of physics. From 1960 until 1990 theoreticians and experimentalists worked together to probe deeper and deeper into the basic structure of reality, moving closer and closer to an understanding of the ultimate building blocks from which everything in the Universe is made. Gerard 't Hooft was closely involved in many of the advances in the development of the subject. In this book he gives a personal account of the process by which physicists came to understand the structure of matter, and to speculate on possible directions in which the subject may evolve in the future. This fascinating personal account of the last thirty years in one of the most dramatic areas in twentieth century physics will be of interest to professional physicists and physics students, as well as the educated general reader with an interest in one of the most exciting scientific detective stories ever.

"The Standard Model and Beyond presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology. The book first reviews calculational techniques in field theory and the status of quantum electrodynamics. It then focuses on global and local symmetries and the construction of non-abelian gauge theories, before explaining the structure and tests of quantum chromodynamics. The book also describes the electroweak interactions and theory, including neutrino masses. The final chapter discusses the motivations for extending the standard model and examines supersymmetry, extended gauge groups, and grand unification. Thoroughly covering gauge field theories, symmetries, and topics beyond the standard model, this text equips readers with the tools to understand the structure and phenomenological consequences of the standard model, to construct extensions, and to perform calculations at tree level. It establishes the necessary background for readers to carry out more advanced research in particle physics."--Publisher's description.
