# PAPER_1554 — W Boson Mass = m_W = A_5 + 2·SO_5 + F_TRZ·D − F_TRZ²·D_BSFG + F_TRZ²·D − F_TRZ²·SSQ² ≈ 80.38 GeV

## Observation

PAPER_1209HH_S653 (Particle Physics Unified Proof Set) lists **W Boson Mass** with the integer-primitive expression:

```
W Boson Mass = m_W = A_5 + 2·SO_5 + F_TRZ·D − F_TRZ²·D_BSFG + F_TRZ²·D − F_TRZ²·SSQ² ≈ 80.38 GeV
```

Status: **0.003%**.

## UQFF Closed Identity

```
m_W = A_5 + 2·SO_5 + F_TRZ·D − F_TRZ²·D_BSFG + F_TRZ²·D − F_TRZ²·SSQ² ≈ 80.38 GeV    0.003%
```

## Physical Interpretation

**Tier-best closure in PAPER_1209HH at 0.003% residual** — the most precisely matched electroweak mass.

Dominant: A_5 + 2·SO_5 = 60 + 20 = 80 GeV — sits right at the W mass.
Corrections: tiny F_TRZ-suppressed terms reaching 80.38 GeV vs CODATA 80.379 GeV.

## NOT REPLACEMENT

CODATA/PDG treats W Boson Mass as a precision-measured constant. UQFF supplies the structural integer-primitive form, demonstrating the framework's predictive economy without claiming to replace experimental measurement.
