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.

After an extensive overview of the Standard Model and of the theory and phenomenology of Supersymmetry, this book describes the recent development of the ATLAS Particle Flow algorithm, a hadronic reconstruction technique aiming at enhancing the sensitivity of the experiment to new physics through the combination of the information from different ATLAS sub-detectors. The first ever ATLAS strong SUSY search exploiting this technique is also described, reporting the results and exclusion limits obtained using the complete proton-proton collision dataset recorded by the ATLAS experiment during the second Run of the Large Hadron Collider (LHC).

This Ph.D. thesis is a search for physics beyond the standard model (SM) of particle physics, which successfully describes the interactions and properties of all known elementary particles. However, no particle exists in the SM that can account for the dark matter, which makes up about one quarter of the energy-mass content of the universe. Understanding the nature of dark matter is one goal of the CERN Large Hadron Collider (LHC). The extension of the SM with supersymmetry (SUSY) is considered a promising possibilities to explain dark matter. The nominated thesis describes a search for SUSY using data collected by the CMS experiment at the LHC. It utilizes a final state consisting of a photon, a lepton, and a large momentum imbalance probing a class of SUSY models that has not yet been studied extensively. The thesis stands out not only due to its content that is explained with clarity but also because the author performed more or less all aspects of the thesis analysis by himself, from data skimming to limit calculations, which is extremely rare, especially nowadays in the large LHC collaborations.

This volume is a compilation of lectures delivered at the TASI 2016 summer school, 'Anticipating the Next Discoveries in Particle Physics', held at the University of Colorado at Boulder in June 2016. The school focused on topics in theoretical particle physics, phenomenology, dark matter, and cosmology of interest to contemporary researchers in these fields. The lectures are accessible to graduate students in the initial stages of their research careers.

This volume contains the proceedings of a meeting held at Imperial College which is devoted to recent developments in string theory, supersymmetry and quantum gravity. The volume comprises two different sections. The first consists of five pedagogical reviews by prominent physicists, covering the currently important subjects of supermembranes, duality, D-branes, new non-perturbative methods and string phenomenology. The second section consists of research reports in these areas and also on other currently important topics such as supersymmetric gauge theories, two-dimensional quantum gravity and black holes.

Modern physics is heady stuff. It seems that barely a week goes by without some new astounding science story; some revelation about hidden dimensions, multiple universes, the holographic principle or incredible cosmic coincidences. But is it true? What evidence do we have for super-symmetric squarks', or superstrings vibrating in an 11-dimensional space-time? How do we know that we live in a multiverse? How can we tell that the universe is a hologram projected from information encoded on its boundary? Doesn't this sound like a fairy story? In Farewell to Reality Jim Baggott asks whether all that we currently know about the universe is based upon science or fantasy. In addition he wonders whether these high priests of fairy tale physics - such as John Barrow, Paul Davies, David Deutsch, Brian Greene, Stephen Hawking, Michio Kaku, Gordon Kane and Leonard Susskind - are the emperor's latest tailors. Praise for Jim Baggott: A shimmering tour d'horizon. Quantum theory may deny us the possibility of properly comprehending physical reality, but Baggott's account is smart and consoling. Kirkus Reviews. Jim Baggott's inspired - and inspiring - idea of presenting the history of quantum physics in terms of 40 key moments works both as an introduction for the uninitiated and as a refresher for anyone who thinks they know the story. John Gribbin. I never read such a good, comprehensive account as Jim Baggott's...highly recommended. A.N. Wilson. The best popular science book of the year to date by far. popularscience.co.uk

This unique volume applies physics and basic science to the mountain environment and is written in a non-technical language for curious laypeople who wonder why or how natural phenomena happen, and what their scientific explanation may be. The book discusses physics in a non-specialized way. Alpine Physics is mostly organized in categories relevant for non-scientists with an interest in alpine environments.Intuitive decision-making is often just grounded in plain common sense, to which mountain and nature lovers relate easily, especially when involving high-stakes decisions based on the estimation of such a treacherous environment. The book highlights how this intuitive decision-making can be complemented and augmented by basic scientific knowledge, and with better understanding it leads one to become a rational decision-maker.The book stimulates its readers to reason and discover why things are the way they are, at high altitudes, where many risk factors are aggravated, often dramatically, by steep gradients. The writing style marries that of the conventional science textbook and that of the informal North-American climbing guidebooks.
