** This 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 explain how particles acquire mass. It is named after physicist **Peter Higgs**, who, along with several others, proposed the existence of this particle in the 1960s. The Higgs Boson is a key component of the **Higgs mechanism**, which describes how particles interact with the **Higgs field**, a fundamental field that permeates all of space. The discovery of the Higgs Boson was a major milestone in the history of physics, confirming a fundamental aspect of the Standard Model and providing evidence for the existence of the Higgs field. The Higgs Boson is a **scalar boson**, meaning it has zero spin and zero electric charge. It is a **heavy particle**, with a mass of approximately 125 GeV (gigaelectronvolts), which is about 133 times the mass of a proton. ## History/Background The concept of the Higgs Boson was first proposed by **Peter Higgs**, **François Englert**, and **Robert Brout** in the 1960s. They suggested that a new field, the Higgs field, was responsible for giving particles mass. The Higgs field is a fundamental field that permeates all of space, and particles interact with it as they move through space. The interaction between particles and the Higgs field causes them to acquire mass. The discovery of the Higgs Boson was a long and challenging process. The **Large Hadron Collider (LHC)**, a powerful particle accelerator located at CERN in Geneva, Switzerland, was built specifically to search for the Higgs Boson. The LHC collided protons at incredibly high energies, producing a vast number of subatomic particles. The ATLAS and CMS experiments, two of the four major experiments at the LHC, were designed to detect the Higgs Boson. ## Key Information The discovery of the Higgs Boson was announced on July 4, 2012, by the ATLAS and CMS experiments. The discovery was confirmed on March 14, 2013, when the two experiments reported their results at a conference in CERN. The Higgs Boson was detected by observing the decay of the Higgs Boson into two **bottom quarks**, which are a type of subatomic particle. The Higgs Boson is a **scalar boson**, meaning it has zero spin and zero electric charge. It is a **heavy particle**, with a mass of approximately 125 GeV (gigaelectronvolts), which is about 133 times the mass of a proton. The Higgs Boson interacts with the **Higgs field**, which is a fundamental field that permeates all of space. The interaction between particles and the Higgs field causes them to acquire mass. ## Significance The discovery of the Higgs Boson is a major milestone in the history of physics, confirming a fundamental aspect of the Standard Model and providing evidence for the existence of the Higgs field. The Higgs Boson is a key component of the **Higgs mechanism**, which describes how particles acquire mass. The discovery of the Higgs Boson has also opened up new areas of research, including the study of the **Higgs field** and its interactions with other particles.

** The **Higgs Boson**, a fundamental particle discovered in 2012, plays a crucial role in the **Standard Model of particle physics**, explaining how particles acquire mass. ## Overview The **Higgs Boson** is an elementary particle predicted by the **Standard Model of particle physics** to be responsible for giving other particles mass. It is named after physicist **Peter Higgs**, who proposed the existence of this particle in 1964. The **Higgs Boson** is a scalar boson, a type of particle that carries a force, and is the quanta of the **Higgs field**, a field that permeates all of space. The **Higgs Boson** was discovered on July 4, 2012, at **CERN** (European Organization for Nuclear Research) in Geneva, Switzerland, using the **Large Hadron Collider (LHC)**, a powerful particle accelerator. The discovery was announced on March 14, 2013, by **CERN** scientists, marking a major milestone in the history of particle physics. ## History/Background The concept of the **Higgs Boson** was first proposed by **Peter Higgs** and **Robert Brout** in 1964, as a way to explain how particles acquire mass. They suggested that a field, now known as the **Higgs field**, permeates all of space and interacts with particles, giving them mass. This idea was later developed by **Gerald Guralnik**, **C. R. Hagen**, and **Tom Kibble**, who also predicted the existence of the **Higgs Boson**. The **Standard Model of particle physics**, which describes the behavior of fundamental particles and forces, was developed in the 1970s. The **Higgs Boson** was predicted to have a mass of around 125 GeV (gigaelectronvolts), which is a unit of energy. The search for the **Higgs Boson** began in the 1980s, but it wasn't until the **LHC** was built in the 2000s that the discovery became possible. ## Key Information The **Higgs Boson** has a mass of approximately 125.09 GeV, which is consistent with the predictions of the **Standard Model**. It is a scalar boson, meaning it has zero spin, and is the quanta of the **Higgs field**. The **Higgs Boson** decays into other particles, such as **b-quarks** and **tau leptons**, and its decay products are detected by sophisticated detectors, such as the **ATLAS** and **CMS** experiments. The discovery of the **Higgs Boson** has confirmed the existence of the **Higgs field**, which is a fundamental aspect of the **Standard Model**. It has also provided evidence for the existence of the **Higgs mechanism**, which explains how particles acquire mass. The discovery has also opened up new areas of research, such as the study of the **Higgs sector**, which is the part of the **Standard Model** that describes the behavior of the **Higgs field**. ## Significance The discovery of the **Higgs Boson** has significant implications for our understanding of the universe. It confirms the existence of the **Higgs field**, which is a fundamental aspect of the **Standard Model**. It also provides evidence for the existence of the **Higgs mechanism**, which explains how particles acquire mass. The discovery has also opened up new areas of research, such as the study of the **Higgs sector**, which is the part of the **Standard Model** that describes the behavior of the **Higgs field**. The discovery of the **Higgs Boson** has also led to a deeper understanding of the **Standard Model** and its limitations. It has also raised new questions, such as the existence of new physics beyond the **Standard Model**, which could explain phenomena such as dark matter and dark energy.
