Quantum Field Theory

This category fixes field quantities, SI conventions, observable meanings and the adoption of specified constructed models. It includes free scalar, Dirac and transverse-photon frameworks, scoped formal QED conventions, soft coherent photon-count predictions and finite-regulator interacting models. Observable domains and smearing conventions are stated explicitly. Mathematical constructions are supplied by the companion category; physical interpretation remains conditional on the model postulates and measurement assumptions identified in each page.

Each main page introduces the objects and assumptions needed for its results, with links to the prerequisites used in the exposition. Its examples companion gives concrete calculations, limiting cases or counterexamples that clarify those hypotheses. Follow prerequisite links when a definition or earlier result is needed, and read the stated scope alongside each conclusion. Local statements distinguish assumptions from deductions and keep the conventions used in calculations visible. The page list below provides entry points into the subject; the order follows the planned progression from foundational definitions to the later applications.
