LIB2-305 · Supply the missing QCD flip energy in the neutron–proton splitting

class OPENmath status (as printed) —attachment (as printed) —scorecard tier word (as printed) none printedhouse tier not yet assignedreview state IN_REVIEWentry version 7

Statement

Can a QCD flip energy complete the neutron–proton mass-difference calculation alongside the existing Coulomb/QED contribution?

Scope

carrierThe QCD flip contribution and the existing Coulomb/QED term
domainThe unpriced physical neutron–proton difference, not the selected isospin Casimir coefficient.
What this does not show. No neutron–proton mass prediction or continuous isospin dynamics follows from the registered parity alone.

Sources in the suite of record

Key — use ≠ record. A review state printed on a source use below names that use — one citation of the suite, read by the lane named in its warrant — not this record. The record's own review state is the one in the table above and is unchanged by any use-level state; a use may be LANE_PROPOSED or REVIEWED while the record it sits on remains IN_REVIEW (R45, R49).

Quotes are verbatim from the sha-pinned text extraction of the Rev33.1 PDF (A1584 §2.2, S309): mathematical typography — radicals, exponents, ≅ — can appear displaced in the extracted line. The PDF page is authoritative; the quote is what the machine gate matched.

The neutron–proton mass difference mn − mp = 1.2933 MeV is unpriced: the framework carries the QED half (Coulomb, with α external) and no QCD half (mu = md at constituent level; the e7 flip carries no energy), so without a flip energy its sign comes out wrong (s1129).

The only registered u ↔ d object is the Os sign map e7 → −e7 (Hu ↔ Hd ; A689 dictionary; read literally, the flip of e7 alone — s1170 shows the phrase also fits full conjugation, and neither map is a Jordan automorphism) — a Z2 parity, not an SU (2)

Open problem

charter refRev32.7 Paper 9 §9, isospin and neutron–proton paragraph, p.133; s1129
failure or reopen conditionWithout the missing flip energy, the source’s wrong-sign result remains; selecting the isospin coefficient does not supply that energy.
obstructionThe registered conjugation has no flip energy, the constituent masses are equal in the stated approximation, and the remaining QED contribution gives the wrong sign by itself.
questionCan the missing QCD flip energy be constructed and combined with the Coulomb/QED contribution?
success conditionSupply the missing QCD flip contribution and a complete calculation of the neutron–proton mass difference, rather than attach an energy to the parity by name.

Why this record is not PUBLISHED (R67, condition T-B)

states a predicateyes
uses on the record · unblocked2 · 2
uses any lane has read2 of 2
REVIEWED SUPPORTS use on the predicate, read by two non-drafting lanesno (0)
a SUPPORTS use on the predicate is DISPUTEDno
machine certificate currentyes

Not PUBLISHED because no use on it has been read as SUPPORTS by two non-drafting lanes on different objects. The transition is written only by the R67 producer and recomputed by a gate on every build; no person promotes a record by hand.

A certificate says the record is well-formed, current, quote-on-page, label-literal, edge-resolved and binding-consistent on the bytes it was issued on. It is not a review, and it goes STALE the moment the master moves under it (R68). It is one conjunct of the PUBLISHED condition (R67), never the whole of it.
