Supersymmetry is an extension of the successful Standard Model of particle physics; it relies on the principle that fermions and bosons are related by a symmetry, leading to an elegant predictive structure for quantum field theory. This textbook provides a comprehensive and pedagogical introduction to supersymmetry and spinor techniques in quantum field theory. By utilising the two-component spinor formalism for fermions, the authors provide many examples of practical calculations relevant for collider physics signatures, anomalies, and radiative corrections. They present in detail the component field and superspace formulations of supersymmetry and explore related concepts, including the theory of extended Higgs sectors, models of grand unification, and the origin of neutrino masses. Numerous exercises are provided at the end of each chapter. Aimed at graduate students and researchers, this volume provides a clear and unified treatment of theoretical concepts that are at the frontiers of high energy particle physics.

This volume presents modern trends in the area of symmetries and their applications based on contributions to the Workshop "Lie Theory and Its Applications in Physics" held in Sofia, Bulgaria (on-line) in June 2021. Traditionally, Lie theory is a tool to build mathematical models for physical systems. Recently, the trend is towards geometrization of the mathematical description of physical systems and objects. A geometric approach to a system yields in general some notion of symmetry which is very helpful in understanding its structure. Geometrization and symmetries are meant in their widest sense, i.e., representation theory, algebraic geometry, number theory, infinite-dimensional Lie algebras and groups, superalgebras and supergroups, groups and quantum groups, noncommutative geometry, symmetries of linear and nonlinear partial differential operators, special functions, and others. Furthermore, the necessary tools from functional analysis are included. This is a big interdisciplinary and interrelated field. The topics covered in this Volume are the most modern trends in the field of the Workshop: Representation Theory, Symmetries in String Theories, Symmetries in Gravity Theories, Supergravity, Conformal Field Theory, Integrable Systems, Quantum Computing and Deep Learning, Entanglement, Applications to Quantum Theory, Exceptional quantum algebra for the standard model of particle physics, Gauge Theories and Applications, Structures on Lie Groups and Lie Algebras. This book is suitable for a broad audience of mathematicians, mathematical physicists, and theoretical physicists, including researchers and graduate students interested in Lie Theory.

Einstein's energy-momentum relation is applicable to particles of all speeds, including the particle at rest and the massless particle moving with the speed of light. If one formula or formalism is applicable to all speeds, we say it is 'Lorentz-covariant.' As for the internal space-time symmetries, there does not appear to be a clear way to approach this problem. For a particle at rest, there are three spin degrees of freedom. For a massless particle, there are helicity and gauge degrees of freedom. The aim of this book is to present one Lorentz-covariant picture of these two different space-time symmetries. Using the same mathematical tool, it is possible to give a Lorentz-covariant picture of Gell-Mann's quark model for the proton at rest and Feynman's parton model for the fast-moving proton. The mathematical formalism for these aspects of the Lorentz covariance is based on two-by-two matrices and harmonic oscillators which serve as two basic scientific languages for many different branches of physics. It is pointed out that the formalism presented in this book is applicable to various aspects of optical sciences of current interest.

This book is devoted to a pedagogical introduction to supergravity from a practical perspective. As a particular feature of the book, the authors provide explicit details, which makes the computations easier to follow for the interested reader. Each chapter has summary tables, which contain the main results and, in addition, we have collected important or additional material in the appendix.In the first part of the book, the N=1 supergravity Lagrangian in four spacetime dimensions is derived. Closely following the reference of Wess and Bagger, we use the superspace approach. All steps, from the geometric principles of curved superspace to the field redefinition necessary to obtain a correctly normalised Lagrangian, are carefully analysed. Comparisons with other methods, such as conformal supergravity, are also given.In the second part of the book, we address more phenomenological aspects of supergravity such as supersymmetry breaking, no-scale supergravity, super-Higgs mechanism, etc. Finally, the relationship between supergravity and particle physics, and cosmology are analysed.

A concise, modern textbook on group theory written especially for physicists Although group theory is a mathematical subject, it is indispensable to many areas of modern theoretical physics, from atomic physics to condensed matter physics, particle physics to string theory. In particular, it is essential for an understanding of the fundamental forces. Yet until now, what has been missing is a modern, accessible, and self-contained textbook on the subject written especially for physicists. Group Theory in a Nutshell for Physicists fills this gap, providing a user-friendly and classroom-tested text that focuses on those aspects of group theory physicists most need to know. From the basic intuitive notion of a group, A. Zee takes readers all the way up to how theories based on gauge groups could unify three of the four fundamental forces. He also includes a concise review of the linear algebra needed for group theory, making the book ideal for self-study.

If classical Lie groups preserve bilinear vector norms, what Lie groups preserve trilinear, quadrilinear, and higher order invariants? Answering this question from a fresh and original perspective, Predrag Cvitanovic takes the reader on the amazing, four-thousand-diagram journey through the theory of Lie groups. This book is the first to systematically develop, explain, and apply diagrammatic projection operators to construct all semi-simple Lie algebras, both classical and exceptional. The invariant tensors are presented in a somewhat unconventional, but in recent years widely used, "birdtracks" notation inspired by the Feynman diagrams of quantum field theory. Notably, invariant tensor diagrams replace algebraic reasoning in carrying out all group-theoretic computations. The diagrammatic approach is particularly effective in evaluating complicated coefficients and group weights, and revealing symmetries hidden by conventional algebraic or index notations. The book covers most topics needed in applications from this new perspective: permutations, Young projection operators, spinorial representations, Casimir operators, and Dynkin indices. Beyond this well-traveled territory, more exotic vistas open up, such as "negative dimensional" relations between various groups and their representations. The most intriguing result of classifying primitive invariants is the emergence of all exceptional Lie groups in a single family, and the attendant pattern of exceptional and classical Lie groups, the so-called Magic Triangle. Written in a lively and personable style, the book is aimed at researchers and graduate students in theoretical physics and mathematics.

Richard Hill and Ernest L. Rossi's The Practitioner's Guide to Mirroring Hands: A Client-Responsive Therapy that Facilitates Natural Problem-Solving and Mind Body Healing describes in detail how Mirroring Hands is conducted, and explores the framework of knowledge and understanding that surrounds and supports its therapeutic process. Foreword by Jeffrey K. Zeig, Ph.D. In this instructive and illuminating manual, Hill and Rossi show you how Mirroring Hands enables clients to unlock their problem-solving and mind body healing capacities to arrive at a resolution in a way that many other therapies might not. The authors offer expert guidance as to its client-responsive applications and differentiate seven variations of the technique in order to give the practitioner confidence and comfort in their ability to work within and around the possibilities presented while in session. Furthermore, Hill and Rossi punctuate their description of how Mirroring Hands is conducted with a range of illustrative casebook examples and stage-by-stage snapshots of the therapy in action: providing scripted language prompts and images of a client's hand movement that demonstrate the processes behind the technique as it takes the client from disruption into the therapeutic; and from there to integration, resolution, and a state of well-being. This book begins by tracing the emergence of the Mirroring Hands approach from its origins in Rossi's studies and experiences with Milton H. Erickson and by presenting a transcription of an insightful discussion between Rossi and Hill as they challenge some of the established ways in which we approach psychotherapy, health, and well-being. Building upon this exchange of ideas, the authors define and demystify the nature of complex, non-linear systems and skillfully unpack the three key elements of induction to therapeutic consciousness focused attention, curiosity, and nascent confidence in a section dedicated to preparing the client for therapy. Hill and Rossi supply guidance for the therapist through explanation of therapeutic dialogue's non-directive language principles, and through exploration of the four-stage cycle that facilitates the client's capacity to access their natural problem-solving and mind body healing. The advocate Mirroring Hands as not only a therapeutic technique, but also for all practitioners engaged in solution-focused therapy. Through its enquiry into the vital elements of client-cue observation, symptom-scaling, and rapport-building inherent in the therapist/client relationship, this book shares great wisdom and insight that will help the practitioner become more attuned to their clients' inner worlds and communication patterns. Hill and Rossi draw on a wealth of up-to-date neuroscientific research and academic theory to help bridge the gap between therapy's intended outcomes and its measured neurological effects, and, towards the book's close, also open the door to the study of quantum field theory to inspire the reader's curiosity in this fascinating topic. An ideal progression for those engaged in mindfulness and meditation, this book is the first book on the subject specially written for all mental health practitioners and is suitable for students of counseling, psychotherapy, psychology, and hypnotherapy, as well as anyone in professional practice.
