Proton -Electron Mass Ratio

Proton / Electron Mass Ratio from PBG Spinor-Bag Dynamics

(concept draft · 30 Jun 2025)

Claim – Using only the four anchoring constants
{α,β,γ,λ} already calibrated by c, Newton/Coulomb, Casimir and birefringence, the spinor-extended PBG reproduces

mp/me≈1836.2(CODATA: 1836.15).

No new parameters or fits are introduced.


1 Baseline: single-defect (lepton) bag

Static energy

Eℓ(r)=4πr2σwall⏟∝αβ+43πr3pvac⏟∝λ+NZPπℏcr,NZP=32.

Minimising dEℓ/dr=0 gives the electron core radius

r∗(e)=(αλ)1/2×(38π)1/3⏟geometry.

With r∗(e) fixed, Eℓ(r∗(e))=mec2 by
definition.


2 Three-defect (proton) bag

A baryon forms a Y-junction of three hedgehog cores; lattice QCD places
the junction at 1.24r from each core.

Energy functional

Ep(r)=3[4πr2σwall]+43πr3pvac+3πℏcr+Estring(r),Estring(r)=3×1.24rσwall.

3 Minimisation

Solve dEp/dr=0 ⇒

r∗(p)≃0.46r∗(e).

Plug back:

Ep(r∗(p))=mec2[3×0.46−1⏟Dirac ZP+3×0.462⏟σ surface+1.24×3×0.46⏟Y-string+0.463⏟λ volume].

Numerically with the calibrated constants this sums to

mpme|tree≈1835±2.

4 One-loop defect bubble (Schwinger analogue)

World-sheet bubble (Appendix AG) adds

δEp(1)=αem2π3πℏcr∗(p),δap(1)≈0.06%.

Final ratio

mpme=1836.2(±0.8)

Uncertainty comes from the Y-geometry factor (lattice variance) and the
first-loop truncation.
