Thank you for your reply but in my case I need to start with Wa=(1/2)EabcdMbcPd And to end with W2=-(1/2)MabMabP2+MacMbcPaPb Could anybody tell me how to derive this

Hi I’m wondering if anybody could help me to prove the result of W2 (square of the pauli-lubanski pseudo-vecor).

Thanks Fredrik I found another book "Quantum Field Theory From Operators to Path Integrals" by Kerson Huang. It has a good explanation about generators of the Poincare group.

Hi I need to find the generators of the Poincare group in the representation of a clasical scalar field. Every textbook I found let them as P and M. But any buk does not what are they. I'm wondering if anybody help me to find this Uda
