I am happy to hear that my calculations are at least conceptually sound. The supposed extra factor of 1/2 in the Majorana Lagrangian puzzles me, though, because in the Majorana representation, the Dirac Lagrangian decomposes into the sum of two independent Lagrangians of the form (1). | |

I am aware of the book by Srednicki, and have been browsing it, but it is not really of interest to me in this connection because it does not treat how to quantize constrained systems; as he writes p. 238: "... requires new formalism for the quantization of constrained systems." In my writings above, I have been adapting the material of Section 7.6, Constraints and Dirac Brackets, of Weinberg's The Quantum Theory of Fields. | |
