TL;DR: The Fortran code SuSpect version 2.1, which calculates the Supersymmetric and Higgs particle spectrum in the Minimal Supers asymmetric Standard Model (MSSM), is presented, which is rather fast and flexible, thus allowing scans of the parameter space with several possible options and choices for model assumptions and approximations.

TL;DR: In this article, the physics case for the ILC was reviewed and the opportunities on Standard Model physics, Higgs physics, Supersymmetry and alternative theories beyond the Standard Model were described.
Abstract: This article reviews the physics case for the ILC. Baseline running at 500 GeV as well as possible upgrades and options are discussed. The opportunities on Standard Model physics, Higgs physics, Supersymmetry and alternative theories beyond the Standard Model are described.

TL;DR: The fundamental laws and principles governing everyday phenomena, some of them manifesting themselves only at scales of time and distance far beyond everyday experience, have been the subject of scientific theories and experiments throughout human history as discussed by the authors.
Abstract: {lg_bullet} What is the universe? How did it begin? {lg_bullet} What are matter and energy? What are space and time? These basic questions have been the subject of scientific theories and experiments throughout human history. The answers have revolutionized the enlightened view of the world, transforming society and advancing civilization. Universal laws and principles govern everyday phenomena, some of them manifesting themselves only at scales of time and distance far beyond everyday experience. Particle physics experiments using particle accelerators transform matter and energy, to reveal the basic workings of the universe. Other experiments exploit naturally occurring particles, such as solar neutrinos or cosmic rays, and astrophysical observations, to provide additional insights.

TL;DR: In this article, a variant of the Randall-Sundrum extra-dimensional model was proposed, where the gauge structure was extended to SU (2 ) L × SU ( 2 ) R × U ( 1 ) X to allow relatively light Kaluza-Klein excitations of the gauge bosons.

TL;DR: The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities.
Abstract: The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities. The ILC has a total footprint of about 31 km and is designed for a peak luminosity of 2x10^34 cm^-2 s^-1. The complex includes a polarized electron source, an undulator-based positron source, two 6.7 km circumference damping rings, two-stage bunch compressors, two 11 km long main linacs and a 4.5 km long beam delivery system. This report is Volume III (Accelerator) of the four volume Reference Design Report, which describes the design and cost of the ILC.

TL;DR: In this paper, the development of Chromium Aluminium Nitride (CrAlN) hard coatings (by varying the nitrogen content in the plasma, the target bias voltage, the working pressure and the deposition time) and their characterization by physical and mechanical techniques (XRD, nanoindentation, Young's modulus, stress, scratch-test, composition, etc.) were discussed.

TL;DR: In this article, it was shown that the charge conjugation and parity (CP) quantum numbers are unambiguously accessible at future e + e -colliders through the measurement of the total cross section and the top polarization in associated Higgs production with top quark pairs.
Abstract: One of the main endeavors at future high-energy colliders is the search for the Higgs boson(s) and, once found, the probe of the fundamental properties. In particular, the charge conjugation and parity (CP) quantum numbers have to be determined. We show that these are unambiguously accessible at future e + e - colliders through the measurement of the total cross section and the top polarization in associated Higgs production with top quark pairs.

TL;DR: In this article, it was shown that the charge conjugation and parity (CP) quantum numbers are unambiguously accessible at future $e+e^-$ colliders through the measurement of the total cross section and the top polarization in associated Higgs production with top quark pairs.

In particular, the charge conjugation and parity (CP) quantum numbers have to be determined. We show that these are unambiguously accessible at future $e^+e^-$ colliders through the measurement of the total cross section and the top polarization in associated Higgs production with top quark pairs.
