[en] A set of articles addresses the discovery of the Higgs boson. In an interview, the chairman of the CERN board recalls the steps which allowed the discovery of the confirmation of the existence of the Higgs boson, a discovery which has been planned since the 1980's and has been made possible by the construction of the LHC (Large Hadron Collider). He also evokes the perspectives for particle physics. An article explains how theory guided the development of experiments as the standard model predicted four production ways and four main disintegration modes for the Higgs boson. The issue of the boson mass is also commented. The next article proposes a brief overview of the parallel histories of theoretical predictions and experimental detections in particle physics since 1905. A fourth article outlines the importance of the design of the collider and of the most adapted detectors to track the boson (notably the Atlas and CMS detectors). The last article addresses the work to be done to assess the boson characteristics and properties

[en] Whereas it is impossible to describe the Big-Bang, stellar structures or matter birth without understanding what is going on at the infinitely small level (quarks, leptons, bosons, and so on), the author reports what is already known and what is being searched for in the infinitely small and infinitely large in order to develop theoretical models to explain black matter, black energy or quantum gravitation. He also presents large international installations which have been designed to perform these studies at the speed of light, and at the limits of matter properties
