** 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.

** 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 subatomic particle predicted by the **Standard Model of particle physics** in the 1960s. It is a scalar boson, a type of elementary particle that plays a crucial role in the fundamental forces of nature. The Higgs Boson is responsible for giving mass to fundamental particles, such as quarks and leptons, which are the building blocks of matter. The existence of the Higgs Boson was confirmed on July 4, 2012, at the **Large Hadron Collider (LHC)** in Geneva, Switzerland. The Higgs Boson is named after physicist **Peter Higgs**, who, along with several other physicists, proposed the existence of a field that permeates all of space and gives mass to fundamental particles. This field is known as the **Higgs field**. The Higgs Boson is the quanta of the Higgs field, and its discovery has confirmed the existence of the Higgs field and the Standard Model of particle physics. ## History/Background The concept of the Higgs Boson was first proposed by **Peter Higgs** and **Felix Bloch** in the 1960s. They suggested that a field, now known as the Higgs field, could be responsible for giving mass to fundamental particles. The Higgs field is a scalar field that permeates all of space and is responsible for the mass of fundamental particles. The Higgs Boson is the quanta of the Higgs field, and its existence was predicted by the Standard Model of particle physics. 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 detect the Higgs Boson, and the search was continued at the **Tevatron** at Fermilab. The Tevatron was also not powerful enough to detect the Higgs Boson, and the search was continued at the LHC. ## Key Information The Higgs Boson is a scalar boson with a mass of approximately **125 GeV** (gigaelectronvolts). It has a spin of 0, which means it is a scalar particle. The Higgs Boson is a fundamental particle that interacts with fundamental particles through the Higgs field. The Higgs field is a scalar field that permeates all of space and is responsible for the mass of fundamental particles. The discovery of the Higgs Boson was announced on July 4, 2012, by the **ATLAS** and **CMS** experiments at the LHC. The discovery was confirmed by the observation of a peak in the **invariant mass spectrum** of particles produced in high-energy collisions. The peak was observed at a mass of approximately 125 GeV, which is consistent with the predicted mass of the Higgs Boson. ## Significance The discovery of the Higgs Boson has confirmed the existence of the Higgs field and the Standard Model of particle physics. The Higgs field is responsible for giving mass to fundamental particles, and the Higgs Boson is the quanta of the Higgs field. The discovery of the Higgs Boson has also confirmed the existence of the **electroweak symmetry breaking**, which is a fundamental concept in the Standard Model of particle physics. The discovery of the Higgs Boson has also opened up new areas of research in particle physics, including the search for new fundamental particles and forces.
