** 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 that plays a crucial role in the **Standard Model of particle physics**. It is responsible for giving mass to fundamental particles, such as quarks and leptons, through a process known as **symmetry breaking**. The Higgs Boson is named after physicist Peter Higgs, who proposed the existence of this particle in the 1960s. The Higgs Boson is a **scalar boson**, meaning it has zero spin and no electric charge. It is a **fundamental particle**, meaning it cannot be broken down into smaller particles. The Higgs Boson is also a **gauge boson**, meaning it is associated with a **gauge symmetry** that is a fundamental aspect of the Standard Model. ## History/Background The concept of the Higgs Boson was first proposed by physicist **Peter Higgs** in 1964, along with several other physicists, including **Felix Bloch**, **Philip Anderson**, and **Gerald Guralnik**. They proposed that a new field, known as the **Higgs field**, was responsible for giving mass to fundamental particles. The Higgs field is a **scalar field** that permeates all of space and is responsible for the **symmetry breaking** that gives mass to particles.
