Answer by fewfew4 for Constructing Dirac's Lagrangian without assuming...
The answer is no. The gamma matrices are defined by the Clifford algebra$$\{\gamma^{\mu},\gamma^{\nu}\}=2\eta^{\mu\nu}$$Let's say we are working in the signature with...

The Dirac $\gamma$ matrices follow the Clifford algebra:\begin{equation*}\{ \gamma^\mu,\gamma^\nu\} = 2\eta^{\mu \nu}\end{equation*}The traditional construction of the Dirac Lagrangian involve choosing...
