A UV-Finite Quantum Field Theory from Event-Density Primitives

This paper argues that quantum field theory is not a starting point but a structural consequence of the Event‑Density (ED) primitive framework. Arc Q shows that once the ED primitives are fixed, the architecture of QFT follows with surprising rigidity. Three results stand out. First, ED forces the existence of a gauge‑type rule‑type whose dynamics reproduce the familiar gauge connection, yielding the first unconditional “this kind of field must exist” prediction of the program. Second, ED forces the canonical creation–annihilation structure of quantum fields, including the boson–fermion divide, without quantisation rules or operator postulates. Third, ED forces ultraviolet finiteness: the infinities of standard QFT are revealed as artefacts of the continuum approximation rather than features of the underlying ontology. Along the way, Arc Q derives the admissible form of interactions, the structure of spontaneous symmetry breaking, the existence of mixing and CP violation, and the vacuum–particle distinction. What ED does not fix—gauge group choice, Higgs details, mass values, coupling constants—falls cleanly on the empirical side. The result is a sharp philosophical picture: QFT’s form is structural, its numbers contingent. Arc Q reframes renormalisation, vacuum structure, and the cosmological constant not as deep mysteries but as artefacts of working at the wrong level of description.
