Boson

Definition

A boson is a particle that follows Bose-Einstein statistics and has an integer spin. These particles are responsible for carrying forces in the quantum field theory.

5 Must Know Facts For Your Next Test

1. Bosons include force carriers like photons, gluons, W and Z bosons, and the Higgs boson.
2. Unlike fermions, multiple bosons can occupy the same quantum state simultaneously.
3. The existence of bosons was first proposed by Indian physicist Satyendra Nath Bose and further developed by Albert Einstein.
4. Bosons play a critical role in mediating interactions between other particles according to the Standard Model of particle physics.
5. The Higgs boson, discovered in 2012 at CERN, provides mass to other particles through the Higgs mechanism.
