The main focus of this year's Proceedings of the 53rd Course of the International School of Subnuclear Physics is the future of physics, including the new frontiers in other fields.

In this thesis, the author develops new high-power millimeter wave techniques for measuring the hyperfine structure of positronium (Ps-HFS) directly for the first time in the world. Indirect measurement of Ps-HFS in the literature might have systematic uncertainties related to the use of a static magnetic field. Development of the millimeter wave devices supports the precise determination of Ps-HFS by directly measuring the Breit-Wigner resonant transition from o-Ps to p-Ps without the magnetic field. At the same time, the width of the measured Breit-Wigner resonance directly provides the lifetime of p-Ps. This measurement is the first precise spectroscopic experiment involving the magnetic dipole transition and high-power millimeter waves. The development of a gyrotron and a Fabry-Pérot cavity is described as providing an effective power of over 20 kW, which is required to cause the direct transition from o-Ps to p-Ps. Those values measured by the newly developed millimeter wave device pave the way for examining the discrepancy observed between conventional indirect experiments on Ps-HFS and the theoretical predictions of Quantum Electrodynamics.

Lincoln, a senior scientist at Fermi National Accelerator Laboratory and adjunct professor of physics at Notre Dame, gives readers an insider's view of the Hadron Collider from its conception, through its early discoveries and difficulties, to its greatest triumph, the discovery of the Higgs boson.

Discover the engineering and science behind particle accelerators, the massive machines that smash the smallest atoms together to observe how they work.

When the discovery of the Higgs Boson at CERN hit the headlines in 2012, the world was stunned by this achievement of modern science. Less well appreciated, however, were the many ways in which this benefited wider society.The Large Hadron Collider — The Greatest Adventure in Town charts a path through the cultural, economic and medical gains of modern particle physics. It illustrates these messages through the ATLAS experiment at CERN, one of the two big experiments which found the Higgs particle. Moving clear of in-depth physics analysis, it draws on the unparalleled curiosity about particle physics aroused by the Higgs discovery, and relates it to developments familiar in the modern world, including the Internet, its successor 'The Grid', and the latest cancer treatments.In this book, advances made from developing the 27 kilometre particle accelerator and its detectors are presented with the benefit of first hand interviews and are extensively illustrated throughout. Interviewees are leading physicists including successive heads of ATLAS, a top historian of science, a highly original economic strategist, a Nobel Prize-winning geneticist and President of the Royal Society in London, and experts in many other fields. These informative and entertaining insights provide both specialists and non-specialists alike with a unique window into the world of modern international research and its often surprising consequences, as exemplified by the ATLAS experiment. The narrative reveals the extent and style of international collaboration necessary to achieve success, and how big companies as well as start-ups enhance their products in the process.

Describes the technology and engineering of the Large Hadron collider (LHC), one of the greatest scientific marvels of this young 21st century. This book traces the feat of its construction, written by the head scientists involved, placed into the context of the scientific goals and principles.

This volume presents a set of pedagogical lectures that introduce particle physics beyond the standard model and particle cosmology to advanced graduate students.
