Deriving the Down-Quark Current Anchor from the Electroweak Completion Scale, Two-Gate Interface Coupling, Phase-Loop Projection, and Colour–Triality Readout
This paper tackles one of the hardest remaining gaps in the VERSF Standard Model programme: the absolute mass scale of the fermions. Earlier mass-grid papers showed that, once the down-quark mass was used as an anchor, much of the quark mass pattern could be organised by compact structural ratios. That was powerful, but still left a weakness: the first number in the grid was imported from experiment. This paper tries to replace that imported anchor with a candidate first-principles projection formula.
In layman’s terms, the paper asks: what is the smallest mass that appears when the electroweak completion interface is read through a colour-carrying quark channel? The answer proposed is that the down-quark current mass is produced by four ingredients working together: the electroweak completion scale, a two-step source-coupling readout, a phase/geometric projection factor, and a colour–triality multiplier. Put together, these give a projected down-quark mass of about 4.695 MeV, very close to the standard quoted down-quark current mass.
The important point is not just the numerical closeness. The paper is trying to show that the number is not a free fit. Each part of the formula is given an owner: the electroweak completion scale comes from the previous electroweak-breaking/completion work; the colour factor comes from the three-colour structure; the triality factor comes from the faithful global gauge quotient; the projection and two-gate coupling factors are named as proof gates that must now be derived. That makes the formula a conditional theorem architecture, not just a nice-looking mass coincidence.
This advances the VERSF Standard Model derivation because it connects the gauge-completion programme to the mass-scale programme. Up to now, VERSF had been building the structure of the Standard Model: matter representations, electroweak completion, colour gauge closure, and the faithful gauge group. This paper begins the next stage: showing how that structure could generate actual fermion masses, not merely the spaces those masses live in.
The paper is also careful about what it does not yet prove. It does not derive the electroweak scale itself, the fine-structure coupling, the full projection kernel, the full RG running, or the heavy-quark pole masses. Instead, it converts one broad weakness — “the down mass is imported” — into a finite set of named proof obligations. That is real progress: the remaining problem becomes sharper, smaller, and more testable.
The most striking new falsifier is the comparison with the electron. If the electron and down quark share the same projection kernel, with the down quark carrying the extra colour–triality factor of 9, then the theory predicts that the down quark should be about nine times the electron mass under the declared readout convention. Current values sit close to that, but not exactly; the paper rightly treats this as a test, not a victory lap. That gives the programme something valuable: a clean place where future lattice QCD and the next VERSF readout theorem can either strengthen the idea or break it.
