Scalar boson

Scalar boson

A scalar boson is a boson whose spin equals zero. Boson means that it has an integer-valued spin; the scalar fixes this value to 0.

The name "scalar boson" arises from quantum field theory. It refers to the particular transformation properties under Lorentz transformation.


  • One very popular quantum field theory, which uses scalar bosonic fields and is introduced in many introductory books to quantum field theories[1] for pedagogical reasons, is the so-called φ⁴-theory. It usually serves as a toy model to introduce the basic concepts of the field.
