Exact mass asymptotics for the two-dimensional O(4) lattice model

OpenAI

For the nearest-neighbor square-lattice O(4) model, the full Osterwalder–Schrader transfer gap, including rotation-invariant local-observable sectors and measured per original lattice time step, is asymptotic to 32 exp(π/4−1/2) √β exp(−πβ) as β tends to infinity.

What was already known

Hasenfratz, Maggiore and Niedermayer predicted the O(4) mass scale in 1990. An earlier OpenAI paper bounded the lattice gap above and below by constant multiples of √β exp(−πβ), without the exact prefactor.

AI involvement AI-led

OpenAI is the credited manuscript author and attributes this family of work to its internal model. Individual proof-development steps and human input are not detailed.

OpenAI is the credited author and the release attributes the family to an internal model; no contrary human-origin account is identified.

Importance Notable

The formula fixes the exact lattice prefactor for the O(4) mass scale.

Limitations

The manuscript imports earlier O(4) bounds and O(3) estimates. A Lean result on O(n) spin-correlation decay does not check this full transfer gap or its prefactor; no completed check of the exact formula is documented.

Technical verification Reported

The exact-prefactor paper is an unformalized manuscript. The Lean classical O(n) theorem covers spin-correlation decay, not this full O(4) transfer gap or constant; no completed human or machine check of the exact asymptotic is documented. Reported is the evidence default.

Human understanding Few

No named human explains the regulator matching and full-sector mass calculation. Few is the evidence default.
