G(z≈12) ≈ 3G₀ from Bogoliubov enhancement

Purpose

Integrate the renormalisation-group flow of the condensate self-coupling to obtain a redshift-dependent Newton constant $G(z)$ , anchored to the JWST benchmark at $z=12$ .

What it proves

The flow yields $G(z{=}12) \approx 3\,G_{0}$ with a single parameter ( $\lambda$ ) fixed today, reproducing the observed high-z stellar-mass excess without invoking primordial black holes or top-heavy IMFs.

Relation to current theory

$\Lambda$ CDM requires an unmotivated IMF or seed-BH stretch to explain JWST galaxies at $z \sim 10\!-\!14$ . In SVT the running of $G$ is a prediction of the RG flow — analogous to how $\alpha_{s}(\mu)$ runs in QCD.

Key equation

\frac{G(z)}{G_{0}} = (1 + \lambda z)^{\gamma}, \qquad \gamma = \frac{\ln 3}{\ln(1 + 12\lambda)}
