Physics Encyclopedia Entry 1780640824
Summary: This entry is about the Higgs Boson, a fundamental particle in the Standard Model of particle physics that explains how other particles acquire mass.
Overview
The Higgs Boson is a scalar boson predicted by the Standard Model of particle physics, a theoretical framework that describes the behavior of fundamental particles and forces in the universe. The Higgs Boson is a key component of the Higgs mechanism, which explains how other particles acquire mass. The discovery of the Higgs Boson in 2012 at the Large Hadron Collider (LHC) confirmed a major prediction of the Standard Model and marked a significant milestone in the history of particle physics.
The Higgs Boson is named after physicist Peter Higgs, who, along with François Englert and Robert Brout, proposed the Higgs mechanism in 1964. 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 zero spin and can interact with other particles through the Weak Nuclear Force.
History/Background
The concept of the Higgs Boson was first proposed in the 1960s by physicists Peter Higgs, François Englert, and Robert Brout, who were working on the Standard Model of particle physics. They proposed that a new field, known as the Higgs field, permeates all of space and gives mass to fundamental particles that interact with it. The Higgs Boson is the quanta of this field, and its discovery was seen as a crucial test of the Standard Model.
The search for the Higgs Boson began in the 1980s, but it wasn't until the construction of the Large Hadron Collider (LHC) in the 2000s that the necessary energy and precision were available to detect it. The LHC, located at CERN in Geneva, Switzerland, is a massive particle accelerator that smashes protons together at nearly the speed of light, creating a vast array of subatomic particles that can be detected and analyzed.
Key Information
The Higgs Boson was discovered on July 4, 2012, by physicists working at the LHC. The discovery was announced on July 4, 2012, and was confirmed by further experiments in 2013. The Higgs Boson is a scalar boson with a mass of approximately 125 GeV, which is consistent with the predictions of the Standard Model.
The Higgs Boson interacts with other particles through the Weak Nuclear Force, which is one of the four fundamental forces of nature. The Higgs Boson is also a key component of the Electroweak Symmetry Breaking mechanism, which explains how the Weak Nuclear Force and Electromagnetic Force are unified at high energies.
Significance
The discovery of the Higgs Boson confirmed a major prediction of the Standard Model and marked a significant milestone in the history of particle physics. The Higgs Boson is a fundamental particle that explains how other particles acquire mass, and its discovery has shed light on the nature of the universe at the smallest scales.
The discovery of the Higgs Boson has also led to a deeper understanding of the Standard Model of particle physics and has paved the way for further research into the Higgs mechanism and the Electroweak Symmetry Breaking mechanism. The Higgs Boson is a key component of the Standard Model, and its discovery has confirmed the validity of this theoretical framework.
