Thanks, what is the rest of the title? Steven Weinberg has written several books...
Is it the 'Quantum Theory of Fields, vol. I"
I think I answered my own question. Thanks.
Hi,
The typical representation of the Dirac gamma matrices are designed for the +--- metric. For example
/gamma^0 = [1 & 0 \\ 0 & -1] , /gamma^i = [0 & /sigma^i \\ - /sigma^i & 0]
this corresponds to the metric +---
Does anyone know a representation of the gamma matrices for -+++...
