Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.

This volume is a compilation of the lectures at TASI 2011, held in Boulder, Colorado, June 2011. They cover topics in theoretical particle physics including the Standard Model and beyond, collider physics, dark matter, and cosmology, at a level intended to be accessible to students at the initial stages of their research careers.

Over the next decade, colliders and telescopes will search for new physics at the terascale. Their discoveries will unveil the fundamental dynamics that operate on length scales of less than an attometer and push our understanding of the early universe back to less than a tenth of a nanosecond after the Big Bang. Indeed, a remarkable synergy between particle physics and astrophysics has emerged with the advent of precision cosmology. Recent measurements from both fields place important constraints on new physics. The research presented here focuses on various aspects of phenomenology in realistic models of electroweak symmetry breaking. The first two chapters examine the constraints imposed on one such model, the Littlest Higgs with T Parity, by precision electroweak measurements from the Large Electron Positron collider and by percent-level measurements of the dark matter relic abundance from the Wilkinson Microwave Anisotropy Probe. A large region of parameter space is found to be consistent with these constraints, and characteristic signals for direct and indirect detection of the generic dark matter candidate are calculated. The final chapter proposes the Higgs cubic coupling as a model-independent collider probe of the viability of electroweak baryogenesis. Barring accidental cancellations, baryogenesis at the terascale would be ruled out unless large deviations in this coupling from its Standard Model value are observed.

In the next few years, particle collider experiments at CERN and dark matter searches throughout the world will directly and indirectly probe the physics of the Terascale. In preparation for these experiments, this thesis examines the possible signals of new physics, and what that new physics might be. We first consider signals of dark matter that depend very little on its underlying nature. We now have precise measurements of the cosmological dark matter abundance; this allows us to predict the flux of high energy gamma rays from dark matter self-annihilation in a generic theory. We also draw attention to a feature in the spectrum that has previously been overlooked: the sharp decrease in the flux at the WIMP mass for photons emitted as final state radiation. This feature, if observed, would provide unambiguous evidence of a non-astrophysical source. We next study a specific theory of new physics, the Littlest Higgs with T Parity. Assuming that this model offers the correct description of dark matter, we predict the expected flux of gamma rays and neutrinos, as well as the direct detection signal. Since each theory has a different pattern of signals, we can use the future experimental data to identify the model that best describes reality. This particular model is well hidden from these detection channels. We then conclude by studying a new possible model for physics at the Terascale, based on combining string theory with the Randall-Sundrum theory of extra dimensions. We develop the theoretical framework for such a model, generalising known results in flat space into an effective field theory in curved space. We then calculate the production and decay of one of the lightest new particles at the Large Hadron Collider in CERN; we find that detection is plausible at that experiment.

As part of the Physics 2010 decadal survey project, the National Research Council was asked by the Department of Energy and the National Science Foundation to recommend priorities for the U.S. particle physics program for the next 15 years. The challenge faced in this study was to identify a compelling leadership role for the United States in elementary particle physics given the global nature of the field and the current lack of a long-term and distinguishing strategic focus. Revealing the Hidden Nature of Space and Time provides an assessment of the scientific challenges in particle physics, including the key questions and experimental opportunities, the current status of the U.S. program and the strategic framework in which it sits and a set of strategic principles and recommendations to sustain a competitive and globally relevant U.S. particle physics program.

These proceedings gather invited and contributed talks presented at the XXII DAE-BRNS High Energy Physics (HEP) Symposium, which was held at the University of Delhi, India, on 12–16 December 2016. The contributions cover a variety of topics in particle physics, astroparticle physics, cosmology and related areas from both experimental and theoretical perspectives, namely (1) Neutrino Physics, (2) Standard Model Physics (including Electroweak, Flavour Physics), (3) Beyond Standard Model Physics, (4) Heavy Ion Physics & QCD (Quantum Chromodynamics), (5) Particle Astrophysics & Cosmology, (6) Future Experiments and Detector Development, (7) Formal Theory, and (8) Societal Applications: Medical Physics, Imaging, etc. The DAE-BRNS High Energy Physics Symposium, widely considered to be one of the leading symposiums in the field of Elementary Particle Physics, is held every other year in India and supported by the Board of Research in Nuclear Sciences (BRNS), Department of Atomic Energy (DAE), India. As many as 400 physicists and researchers attended the 22nd Symposium to discuss the latest advances in the field. A poster session was also organized to highlight the work and findings of young researchers. Bringing together the essential content, the book offers a valuable resource for both beginning and advanced researchers in the field.
