** This encyclopedia entry is about the **Higgs Boson**, a fundamental particle in the Standard Model of particle physics, discovered in 2012 at the Large Hadron Collider (LHC). ## Overview The **Higgs Boson** is a scalar boson predicted by the **Standard Model of particle physics** to be responsible for giving other particles mass. It is named after physicist Peter Higgs and his colleagues, who proposed the existence of this particle in the 1960s. The Higgs Boson is a key component of the Higgs mechanism, which explains how fundamental particles acquire mass. In the Standard Model, the Higgs field is a field that permeates all of space and is responsible for giving mass to fundamental particles that interact with it. The Higgs Boson is the quanta of this field, and its discovery confirmed the existence of the Higgs field and the Higgs mechanism. The Higgs Boson is a crucial component of the Standard Model, and its discovery has far-reaching implications for our understanding of the universe. The search for the Higgs Boson was a major undertaking in particle physics, involving thousands of scientists and engineers from around the world. The discovery of the Higgs Boson was announced on July 4, 2012, by physicists at CERN, the European Organization for Nuclear Research, who had been operating the Large Hadron Collider (LHC) in Geneva, Switzerland. ## History/Background The concept of the Higgs Boson was first proposed by physicists Peter Higgs, François Englert, and Robert Brout in the 1960s. They proposed that a scalar field, now known as the Higgs field, was responsible for giving mass to fundamental particles. The Higgs field is a field that permeates all of space and is responsible for giving mass to particles that interact with it. In the 1970s, physicists discovered that the Higgs field was a crucial component of the Standard Model of particle physics. The Standard Model is a theoretical framework that describes the behavior of fundamental particles and forces in the universe. The Higgs Boson is a key component of the Standard Model, and its discovery confirmed the existence of the Higgs field and the Higgs mechanism. The search for the Higgs Boson was a major undertaking in particle physics, involving thousands of scientists and engineers from around the world. The Large Hadron Collider (LHC) was built at CERN to search for the Higgs Boson and other fundamental particles. The LHC is a circular tunnel that is 27 kilometers in circumference and is used to accelerate protons to nearly the speed of light. ## Key Information The Higgs Boson is a scalar boson with a mass of approximately 125 GeV (gigaelectronvolts). It is a fundamental particle that is responsible for giving mass to other particles that interact with it. The Higgs Boson is a key component of the Standard Model of particle physics and is a crucial component of the Higgs mechanism. The discovery of the Higgs Boson was announced on July 4, 2012, by physicists at CERN. The discovery was made using data from the ATLAS and CMS experiments at the LHC. The ATLAS and CMS experiments are two of the four major experiments at the LHC, and they were designed to search for the Higgs Boson and other fundamental particles. The discovery of the Higgs Boson was a major breakthrough in particle physics and confirmed the existence of the Higgs field and the Higgs mechanism. The Higgs Boson is a crucial component of the Standard Model, and its discovery has far-reaching implications for our understanding of the universe. ## Significance The discovery of the Higgs Boson is a major milestone in the history of particle physics and has far-reaching implications for our understanding of the universe. The Higgs Boson is a fundamental particle that is responsible for giving mass to other particles that interact with it, and its discovery confirmed the existence of the Higgs field and the Higgs mechanism. The discovery of the Higgs Boson has also opened up new avenues of research in particle physics. The Higgs Boson is a key component of the Standard Model, and its discovery has confirmed the existence of the Higgs field and the Higgs mechanism. The Higgs Boson is also a crucial component of the search for new physics beyond the Standard Model.
