Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain quantum field theory and its core ideas, relay its established results and the Standard Model from physics references, distinguish established theory from speculative extensions with attribution, and point to learning resources.

The theoretical framework combining quantum mechanics, special relativity and classical field theory in which particles are excitations of underlying fields, providing the language of the Standard Model of particle physics through quantum electrodynamics and quantum chromodynamics, of condensed matter physics, and of extensions such as conformal field theory, grand unified theories, Little Higgs, 331 and bumblebee models that go beyond established physics; quantum field theory is among the most precisely tested frameworks in science.

What it is for: Not applicable; a theoretical framework.

It can be explain core ideas; relay established results; distinguish speculative extensions; point to learning resources.

Distinguishing features

Fields as fundamental

Renormalisation

Gauge symmetry

Extreme precision

What it looks like

Not a visible object; mathematical formalism and Feynman diagrams.

Physical character

QED electron magnetic moment agreement: about 1 part in 10^12 precision - theory versus experiment

How it is recognised

Framework of particles as field excitations

QED, QCD, Standard Model, conformal and unified theories

Quantum mechanics is non-relativistic; general relativity is not yet quantised; string theory is a candidate beyond QFT

What the second pass must settle

  • Should the Standard Model be the primary linked entry?
  • How should textbooks and reviews be linked?
  • The registry entry has merged aliases naming speculative models and an unclear term; should they be split off?
