Physics Encyclopedia Entry 1781151785
Summary: The Physics Encyclopedia Entry 1781151785 refers to the discovery of the Higgs Boson, a fundamental particle in the Standard Model of particle physics that explains how particles acquire mass.
Overview
The Higgs Boson is a scalar boson predicted by the Electroweak Symmetry Breaking theory, which describes the fundamental forces of nature. The discovery of the Higgs Boson was a groundbreaking achievement in modern physics, confirming a key aspect of the Standard Model. The Higgs Boson is named after physicist Peter Higgs, who, along with François Englert and Robert Brout, proposed the existence of this particle in the 1960s.
The Higgs Boson is a massive particle with a mass of approximately 125 GeV (gigaelectronvolts), which is about 133 times the mass of a proton. It is a scalar boson, meaning it has no spin, and it interacts with other particles through the Higgs field, a fundamental field that permeates all of space. The Higgs field is responsible for giving mass to fundamental particles, such as quarks and leptons, which are the building blocks of matter.
History/Background
The concept of the Higgs Boson was first proposed by Peter Higgs and his colleagues in 1964, as a way to explain how particles acquire mass. They proposed that a new field, the Higgs field, would permeate all of space and interact with fundamental particles, giving them mass. The Higgs Boson was predicted to be a massive particle that would be produced in high-energy collisions, such as those occurring in particle accelerators.
The search for the Higgs Boson began in the 1980s, with the construction of the Large Electron-Positron Collider (LEP) at CERN. However, the LEP was not powerful enough to produce the Higgs Boson, and the search was continued at the Tevatron at Fermilab. The discovery of the Higgs Boson was finally announced on July 4, 2012, by the ATLAS and CMS experiments at CERN's Large Hadron Collider (LHC).
