The best way to study the existence of the Higgs boson, supersymmetry and grand unified theories, and perhaps the physics of dark matter and dark energy, is at the TeV scale. This is the energy scale ...that will be explored at the Large Hadron Collider. This machine will generate the energy and rate of collisions that might provide evidence of new fundamental physics. It also brings with it the formidable challenge of building detectors that can record a large variety of detailed measurements in the inhospitable environment close to the collisions points of the machine.

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity ...and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work.

This open access book celebrates the contribution of Bruno Touschek to theoretical physics and particle colliders in Europe. It contains direct testimonials from his former students, collaborators, ...and eminent scientists, among them, two Nobel Prize winners in Physics, Giorgio Parisi and Carlo Rubbia. It reviews the main developments in theoretical and accelerator physics in the second half of the twentieth century, while at the same time providing an overview of future prospects worldwide. This book is unique in that it will be of interest to historians of physics and also to the younger generation of researchers. Through the contribution of the leading protagonists, the interested scholar will learn about the past, present status, and relevance of both theoretical and experimental accelerator physics. The overview of Bruno Touschek’s life and works across Europe, from pre-war Vienna to Germany, the UK, Italy, and France, adds a human dimension to the scientific narration, while the open access status makes this laudatory book available to anyone with interest.
An MgB2 superconducting solenoid magnet has been developed for electron beam focusing in X-band (12 GHz) klystrons for particle accelerator RF systems, to provide a cen-tral field of 0.8 T at 57 A ...and at ≥ 20 K. It has successfully real-ized significant AC-plug power saving in one order of magni-tude compared with that for a conventional Cu solenoid mag-net. A large-scale application may be expected for the Compact Linear Collider (CLIC) project proposed as a candidate of fu-ture accelerators at CERN. It requires {\sim 5,000} klystrons, and the MgB2 magnet application may realize significant AC-plug power saving. This paper describes progress in a prototype MgB2 superconducting solenoid magnet development and will discuss the future prospect.
A search for a narrow scalar resonance decaying into an opposite-sign muon pair produced in events with and without b-tagged jets is presented in this paper. The search uses 36.1 fb−1 of s√=13 TeV ...proton-proton collision data recorded by the ATLAS experiment at the LHC. No significant excess of events above the expected Standard Model background is observed in the investigated mass range of 0.2 to 1.0 TeV. The observed upper limits at 95% confidence level on the cross section times branching ratio for b-quark associated production and gluon-gluon fusion are between 1.9 and 41 fb and 1.6 and 44 fb respectively, which is consistent with expectations.
