QFT, weinberg volume 1 page 66

In summary, QFT (Quantum Field Theory) is a theoretical framework that combines the principles of quantum mechanics and special relativity to describe the behavior of particles at a subatomic level. Weinberg volume 1 page 66 is a section of the book "The Quantum Theory of Fields" that discusses the basics of QFT. The equations on this page represent the mathematical formalism of QFT, including the Lagrangian density and Feynman rules. QFT has been extensively tested and has practical applications in fields such as particle physics and technology development. However, it is still considered a theoretical framework and efforts are ongoing to unify it with other theories.

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...
