- \((-i\gamma^\mu\partial_\mu + m) \psi = 0\)
http://bomber0.byus.net/index.php/2009/06/24/1336
Let there be light.
Start with the relativistic wave equation (Dirac equation).
- \((-i\gamma^\mu\partial_\mu + m) \psi = 0\)
Choose a Lagrangian.
\(\mathcal{L} = i \bar{\psi} \gamma^\mu \partial_\mu \psi -m \bar{\psi} \psi\)
We need a \(U(1)\) - local gauge invariance.
\(\psi(x) \to e^{i\alpha(x)}\psi(x)\)
To obtain the local gauge invariance, introduce a new gauge field and get
\(\mathcal{L}=i \bar{\psi} \gamma^\mu \partial_\mu \psi - q \bar{\psi}\gamma^{\mu} A_{\mu} \psi -m \bar{\psi} \psi - \frac{1}{4}F_{\mu\nu}F^{\mu\nu}\)
and there was light. God saw that the light was good.

클리포드 대수
\(\left\{ \gamma^\mu , \gamma^\nu \right\} = \gamma^\mu \gamma^\nu + \gamma^\nu \gamma^\mu = 2g^{\mu \nu}\)
