Higgs boson theory12/30/2023 ![]() ![]() It represents the product of efforts by researchers, engineers and technicians from all continents working together for a common cause. The discovery is, indeed, exciting for all of humanity. He said, "It was a once-in-a-lifetime privilege to be physically present and to share the excitement with the hundreds of other scientists who have been closely following the experiments at CERN. Quevedo attended the seminar at CERN on 4 July, and the announcement was also broadcast live at ICTP. ![]() All new particles to be discovered from now on will indicate the existence of new physical principles. Its discovery marks a turning point between established physical knowledge and new physics. The Higgs particle was the only missing particle needed to confirm the Glashow-Salam-Weinberg model of electromagnetic and weak interactions, one of the two cornerstones of the standard model of elementary particles. It is clear then that scientists from developing countries - including Salam, from Pakistan, and Bose from India - have made fundamental contributions to theoretical physics. The particle just discovered seems to be the particular Higgs boson predicted by Salam and Weinberg, using the general mechanism of Higgs and others, in their model describing the electromagnetic and weak interactions.īosons in general were named after the great self-taught Indian mathematical-physicist Satyendra Nath Bose, who, together with Einstein, described their behaviour. Higgs and a handful of other theoretical physicists discovered the general mechanism for which the Higgs bosons are responsible for endowing other particles with mass. Salam and Weinberg anticipated the existence of this particle, though it is named after the British professor Peter Higgs, who first identified the general class of particles. Yet important steps towards this important discovery were made by the founder of ICTP and TWAS, Abdus Salam, for which he was awarded the 1979 Nobel Prize in Physics, along with Sheldon Glashow and Steven Weinberg, "for their contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current." The great excitement in the community of experimental and theoretical high-energy physicists is not easy to explain to non-experts. The announcement of the discovery of a new elementary particle with the properties of the long-searched for Higgs boson on 4 July 2012 at the European Organization for Nuclear Research (CERN) auditorium, was one of the most important announcements to be made in physics in the past decades.
