Scientists associated with the European Laboratory for Particle Physics (CERN) just got their hands on it First evidence of very rare behavior of the Higgs boson: the decay — the gradual decrease in activity of a sample of a substance containing radioactive material — of a particle into a Z boson and a photonany new particle that corresponds to the Higgs Boson.
By merging ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC), the observations have been designated a “historic breakthrough.” By the Director General of the European Center for Nuclear Research, Rolf Heuer, who believes that the discovery could become a key to understanding the formation of the universe.
Known as the “God Particle”, Discovery of the Higgs Boson at CERN’s LHC in 2012, represents a milestone in the field of particle physics. Since then, it has become a collaboration between ATLAS and CMS He has been investigating the properties of this individual particle and has tried to identify the different ways in which it is produced and broken down into other particles.
Scientists from this collaboration recently reported joining efforts to find the first evidence of the rare process by which the Higgs boson decays into a bosonthe electrically neutral carrier of the weak force, And in the photonthe carrier of the electromagnetic force.
The phenomenon of Higgs Boson decay It could provide indirect evidence for the existence of particles beyond those predicted by the Standard Model of particle physics, CERN shows..
Portugal was a partner of CERN, namely through ISQ, which for six years has carried out activities in several countries, regarding the manufacture of components and the assembly of Cryo Dipoles to complete the 27 km loop of the Large Hadron Collider (LHC).
ISQ Consulting functions and responsibilities included reviewing technical specifications for the quality of cryogenic magnets; Consultancy to organize CERN’s quality assurance system for the project, including the computerized system for controlling and monitoring inspections and tests to ensure traceability.
The ISQ also ensured the quality check of the manufacture of cryogenic magnets, covering various components (cables, superconducting magnets, coolers and cryogenic components) and their installation at CERN and in the tunnel itself. 26 ISQ engineers and inspectors, qualified in different specialties, who carried out more than 200,000 hours of inspection and testing, participated in this project.
