SciencePhysics Encyclopedia Entry 1775879524
** This encyclopedia entry is about 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 **Standard Model of particle physics** to be responsible for the **electromagnetic force** and the **weak nuclear force**. It is named after physicist **Peter Higgs**, who proposed its existence in 1964. The Higgs Boson is a crucial component of the **Higgs mechanism**, which explains how particles acquire mass. In essence, the Higgs Boson acts as a **"cosmic molasses"** that slows down particles, giving them mass. The Higgs Boson is a **scalar boson**, meaning it has zero spin and no electric charge. It is the only fundamental particle in the Standard Model that has not been directly observed until its discovery in 2012. The Higgs Boson is a **short-lived particle**, decaying into other particles almost instantly after its creation. ## History/Background The concept of the Higgs Boson was first proposed by **Peter Higgs** and **Felix Bloch** in 1964. They suggested that a new field, now known as the **Higgs field**, permeates all of space and gives mass to fundamental particles. The Higgs Boson is the **quantum of this field**, and its existence was predicted to be a **scalar boson**. The search for the Higgs Boson began in the 1980s, with the **Large Electron-Positron Collider (LEP)** at CERN. Although LEP was not powerful enough to detect the Higgs Boson, it laid the groundwork for future experiments. The **Large Hadron Collider (LHC)**, which began operation in 2008, was designed to detect the Higgs Boson. After years of searching, the Higgs Boson was finally detected on **July 4, 2012**, by the **ATLAS** and **CMS** experiments at the LHC. ## Key Information The Higgs Boson has a **mass of approximately 125 GeV** (gigaelectronvolts), which is about 133 times the mass of a proton. It decays into other particles, such as **bottom quarks** and **tau leptons**, almost instantly after its creation. The Higgs Boson is a **scalar boson**, meaning it has zero spin and no electric charge. The discovery of the Higgs Boson confirmed the **Higgs mechanism**, which explains how particles acquire mass. This discovery has far-reaching implications for our understanding of the universe, from the **origin of the universe** to the **behavior of subatomic particles**. ## Significance The discovery of the Higgs Boson is a **landmark moment** in the history of physics, confirming the **Standard Model of particle physics**. It has opened up new avenues of research, including the study of the **Higgs field** and its role in the universe. The Higgs Boson has also sparked new interest in **particle physics**, inspiring a new generation of physicists to explore the mysteries of the universe.
