Home > Dirac field

In physics, a Dirac field is a fermionic field (usually a quantized field, as usual in quantum field theory) associated with spin 1/2 fermions such as the electron or muon.

The Dirac field transforms as the unconstrained spinor, and it satisfies the Dirac equation. The usual free Lagrangian for the Dirac field is

The Dirac fields are important components of Quantum electrodynamics and the Standard model.

A Dirac field is equivalent to two Majorana field s with the same mass.

A massless Dirac field is equivalent to two (massless) Weyl field s.

Dirac delta functionThe Dirac delta function introduced by Paul Dirac, can be informally thought of as a function δ x that has the value of infinity for x 0, the value zero elsewhere, and a total integral of one. The graph of the delta function can be thought of as fol	Dirac equationThe Dirac equation is a relativistic quantum mechanical wave equation invented by Paul Dirac in 1928.
