# Difference Between Gauge Boson And Higgs Boson

Let us look at the between Gauge Bosons and the Higgs Boson through their definitions, characteristics, roles in particle interactions, experimental verifications, and broader implications for our comprehension of the cosmos.

## What is Gauge Boson?

In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. Elementary particles whose interactions are described by a gauge theory interact with each other by the exchange of gauge bosons, usually as virtual particles.

In other words, Gauge bosons are elementary particles that are responsible for mediating the fundamental forces of nature according to the Standard Model of particle physics. These forces include electromagnetism, the weak nuclear force, and the strong nuclear force. Gauge bosons interact with other particles, transmitting the forces between them. They are associated with specific gauge fields, which are fundamental fields that describe the interactions between particles.

In the Standard Model, there are four known types of gauge bosons:

• Photon (γ): Mediates the electromagnetic force, responsible for interactions between charged particles.
• Gluon (g): Mediates the strong nuclear force, which binds quarks together to form protons, neutrons, and other hadrons.
• W and Z bosons (W⁺, W⁻, Z⁰): Mediate the weak nuclear force, responsible for processes such as beta decay and neutrino interactions.

Gauge bosons are characterized by their integer spin (1 for the gauge bosons in the Standard Model) and can carry various types of charges, such as electric charge, color charge, or weak isospin, depending on the force they mediate

## What is Higgs Boson?

The Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory.

In other words, The Higgs boson is an elementary particle in the Standard Model of particle physics. It was proposed as a key component of the mechanism that gives particles their mass. The Higgs boson is associated with the Higgs field, which permeates all of space.

The Higgs boson itself is a massive particle with a mass of approximately 125 GeV/c². Its discovery was confirmed in 2012 by experiments conducted at the Large Hadron Collider (LHC) at CERN. The Higgs boson has a spin of 0, making it a scalar boson. This distinguishes it from other particles like gauge bosons (which have integer spin) and fermions (which have half-integer spin).

The existence of the Higgs boson is tied to the Higgs mechanism, which explains how elementary particles acquire mass. According to this mechanism, particles interact with the Higgs field, and their interaction results in the particles gaining mass.

The Higgs mechanism is responsible for the spontaneous breaking of the electroweak symmetry in the early universe. This symmetry breaking is essential for the weak force and electromagnetic force to have different strengths and behaviors at low energies.

The discovery of the Higgs boson confirmed the existence of the Higgs field and provided experimental validation for the mechanism by which particles acquire mass. Also, the Standard Model of particle physics, which describes the fundamental particles and their interactions, was further solidified. It completed the missing piece in the theory, as the existence of the Higgs boson was predicted by the Standard Model.

## Key Takeaways

Both the field and the boson are named after physicist Peter Higgs, who in 1964, along with five other scientists in three teams, proposed the Higgs mechanism, a way for some particles to acquire mass. (All fundamental particles known at the time should be massless at very high energies, but fully explaining how some particles gain mass at lower energies had been extremely difficult.) If these ideas were correct, a particle known as a scalar boson should also exist (with certain properties). This particle was called the Higgs boson and could be used to test whether the Higgs field was the correct explanation.

Photons, W and Z bosons, and gluons are gauge bosons. All known gauge bosons have a spin of 1; for comparison, the Higgs boson has spin zero and the hypothetical graviton has a spin of 2. Therefore, all known gauge bosons are vector bosons.

Gauge bosons are different from the other kinds of bosons: first, fundamental scalar bosons (the Higgs boson); second, mesons, which are composite bosons, made of quarks; third, larger composite, non-force-carrying bosons, such as certain atoms.
