SUMMARY

The discussion focuses on proving scalar products for arbitrary momenta as presented in Weinberg's Volume 1, specifically on page 66. The user is struggling with the expression N(p)N*(p')(D(L^-1(p)L(p'))_rowrow'detla and has spent considerable time attempting to validate it. The lack of responses indicates a need for clearer articulation of the problem or additional context to facilitate assistance.

PREREQUISITES
  • Understanding of quantum field theory (QFT)
  • Familiarity with scalar products in momentum space
  • Knowledge of the notation and concepts in Weinberg's QFT texts
  • Basic grasp of linear algebra and determinants
NEXT STEPS
  • Review scalar product definitions in quantum field theory
  • Study the implications of Lorentz transformations on momentum
  • Examine examples of scalar products in QFT literature
  • Explore the mathematical properties of determinants in linear transformations
USEFUL FOR

Students and researchers in quantum field theory, particularly those grappling with advanced concepts in scalar products and momentum transformations.

hi guys, this is the first time i post a thread.

I have an issue on proving the scalar products for arbitrary momenta. Can anyone help me ?

I always end up with N(p)N*(p')(D(L^-1(p)L(p'))_rowrow'detla

I have been spending hours on proving this..still i can't prove it...
