## Abstract

Derives the UQFF phonon-suppressed gravitational wave strain for the GW190425 binary neutron star
merger: h_UQFF(t) = h_GR(t) * D_total * exp([SSq]*t/26), where D_total = 0.530 represents a 47%
strain damping via phonon-vacuum coupling at 1.25 THz. The suppression factor arises from the
26-layer polylog structure redistributing gravitational wave energy into phonon modes. Time
evolution through exp([SSq]*t/26) provides dynamical strain modification during the inspiral.
GW190425's mass-gap nature (M_chirp ~ 1.44 M_sun) makes it the ideal testbed for phonon effects at
the NS-BH boundary.

## 1. Core Equations

### Section A: Lagrangian

$$
\begin{aligned}
  & h_UQFF(t) = h_GR(t) * D_total * exp([SSq] * t / 26) \\
  & D_total = 0.530  (UQFF phonon suppression factor) \\
  & h_GR = 3.0e-22  (GR strain at d_L ~ 159 Mpc) \\
  & [SSq] = 0.57  (calibrated coupling constant)
\end{aligned}
$$

### Section B: VDS/DVP/BH Number Systems

$$
\begin{aligned}
  & VDS: D_total = Product_{k=1}^{26} (1 - [SSq]*Phi_k/(26*Phi_0)) \\
  & DVP: h_n = h_GR * Product_{k=1}^{n} D_k  (layer-by-layer suppression) \\
  & BH: Lambda_tidal^phonon = Lambda_GR * (1 + Phi*S_26*[SSq]/N)
\end{aligned}
$$

### Section SM: SM Anchors

$$
\begin{aligned}
  & M1 = 1.7 M_sun, M2 = 1.5 M_sun  (GW190425 component masses) \\
  & M_chirp = (M1*M2)^(3/5) / (M1+M2)^(1/5) ~ 1.44 M_sun \\
  & d_L ~ 159 Mpc  (luminosity distance) \\
  & f_GW = 20-300 Hz  (LIGO band)
\end{aligned}
$$

## 2. Parameters

| Parameter | Default | Description |
|-----------|---------|-------------|
| h_GR | 3.0e-22 | GR strain amplitude |
| D_total | 0.530 | Suppression factor |
| t | 0 s | Observation time |
| f_GW | 300 Hz | GW frequency |

---

## 3. Key Results

| Configuration | h_UQFF | Suppression |
|---------------|--------|-------------|
| D_total = 0.530 | 1.59e-22 | 47.0% |
| D_total = 0.333 | 1.00e-22 | 66.7% |
| D_total = 0.667 | 2.00e-22 | 33.3% |

---

## 4. Physical Interpretation

The 47% strain suppression for GW190425 implies that nearly half the gravitational wave energy is
redistributed into phonon vacuum modes during propagation through the 26-layer UQFF structure. This
is consistent with the GW170817 result (66.7% suppression, PAPER_916) when accounting for the
different chirp masses and distances. The mass-gap nature of GW190425 (total mass 3.2 M_sun, above
typical NS-NS but below confident BH formation) may reflect phonon-mediated stability at the NS-BH
transition, where vacuum buoyancy provides additional pressure support.

### Session 225 Phonon-Physics Upgrade: GW Strain Modulation

> *Upgrade from PAPER_1000 (NS Merger Phonon Suppression) and PAPER_1022
> (GW Phonon Strain SCm Modulation). See also PAPER_1011-1012 for
> GW170817/GW190425 upgraded analyses.*

The late-corpus phonon analysis (Sessions 219-225) reveals that the SCm
vacuum field modulates gravitational-wave strain via a frequency-dependent
suppression factor.  The corrected strain amplitude is:

$$h_{\text{UQFF}}(\Gamma) = h_{\text{GR}} \cdot \left(1 - 0.47\,\frac{\Phi(\Gamma)}{S_{26}^{(3)}}\right)$$

where:
- $\Phi(\Gamma) = \cos(\omega_{\text{SCm}} \cdot t) \cdot \Theta(H_{\text{SCm}} - 0.5)$ is the phonon modulation factor
- $\omega_{\text{SCm}} = 2\pi \times 1.25\;\text{THz}$ is the SCm phonon resonance frequency
- $S_{26}^{(3)} = \sum_{n=0}^{\infty} \frac{(1/4)_n\,(1/2)_n\,(3/4)_n}{(n!)^3} \cdot \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$ is the third-order Ramanujan summation
- $\Theta$ is the Heaviside step ensuring $H_{\text{SCm}} \geq 0.5$ (phase-transition threshold)

**Physical mechanism:** The 1.25 THz phonon field of the SCm vacuum creates
a standing-wave pattern that partially decouples the metric perturbation from
the radiation zone, producing a 47% peak strain reduction for optimally
oriented NS mergers.  The BCS gap energy $\Delta E_{\text{BCS}}$ of the
neutron-star crust couples to this phonon field, creating a mass-gap
classifier that distinguishes NS from BH remnants at $M \approx 2.5\,M_\odot$.

**Calibration (canonical):** $\kappa = 5 \times 10^{-4}\;\text{day}^{-1}$,
$[\text{SSq}] = 0.57$, $\beta_i = 0.603$, $H_{\text{SCm}} \approx 0.99$.

### Session 225 Phonon-Physics Upgrade: Yang-Mills BCS Phonon Mass Gap

> *Upgrade from PAPER_1318 (Yang-Mills Mass Gap via SCm BCS Phonon) and
> PAPER_1070 (Yang-Mills Mass Gap VDS Bridge).  See also PAPER_1004
> (QGP Vacuum Density), PAPER_1007 (Deconfinement Phase Diagram),
> PAPER_1059 (CGC BK Saturation), PAPER_1064 (Resummation BFKL/Sudakov).*

The late-corpus analysis derives the Yang-Mills mass gap via a BCS-like
phonon pairing mechanism in the SCm vacuum:

$$\Delta_{\text{YM}} = \Lambda_{\text{QCD}} \cdot \exp\!\left(-\frac{1}{\alpha_s(T) \cdot N_c}\right) \cdot S_{26}^{(3)}$$

where the running coupling evolves as:
$$\alpha_s(T) = \frac{\alpha_{s,0}}{1 + \alpha_{s,0} \cdot b_0 \cdot \ln(T/T_c)}, \qquad b_0 = \frac{11 N_c - 2 N_f}{12\pi}$$

**Physical mechanism:** The SCm phonon field ($\omega_{\text{SCm}} = 1.25\;\text{THz}$)
provides a pairing interaction analogous to the BCS electron-phonon coupling in
superconductors.  Gluons acquire an effective mass through condensate formation
in the SCm-modified vacuum, yielding a non-perturbative gap $\Delta_{\text{YM}} \approx 1.736\;\text{GeV}$ (PAPER_1318 integer-primitive closure; lattice QCD anchor 1.7 GeV; supersedes 1.736 GeV registry-bug value).

**VDS bridge (PAPER_1070):** The vacuum density series links the gap to the
26-level hierarchy: $\Delta \propto \rho_{\text{VDS}}^{1/4} \cdot (1 + [\text{SSq}] \cdot n/26)$
where the VDS sub-ratio 0.108 places confinement in the sub-threshold regime.

**QGP transition (PAPER_1004/1007):** At $T > T_c \approx 170\;\text{MeV}$, the phonon
coupling weakens ($\alpha_s \to 0$) and the gap closes, reproducing the
deconfinement phase transition observed at ALICE/LHC.

### Session 225 Phonon-Physics Upgrade: UQFF 9-Sector Lagrangian

> *Upgrade from PAPER_1066 (UQFF Lagrangian First Principles) and
> PAPER_1065 (Buoyancy Lagrangian EOM Variational Derivation).*

The complete UQFF Lagrangian density, from which all sector-specific
equations of motion derive:

$$\mathcal{L}_{\text{UQFF}} = \mathcal{L}_{\text{GR}} + \mathcal{L}_{\text{SCm}} + \mathcal{L}_{\text{phonon}} + \mathcal{L}_{\text{interaction}}$$

$$\mathcal{L}_{\text{SCm}} = \tfrac{1}{2}(\partial_\mu \phi)^2 - \lambda\bigl(\phi^2 - v_{\text{SCm}}^2\bigr)^2$$

The SCm condensate potential minimum gives $V(\phi_0) = -7.09 \times 10^{-37}\;\text{J/m}^3$
(matching $\rho_{\text{SCm}}$) and phonon mass $m_{\text{phonon}} = \sqrt{8\lambda}\,v_{\text{SCm}}$.

**Nine-sector closure (Session 202):**
$$\mathcal{L}_{9} = \mathcal{L}_{\text{EH}} + \mathcal{L}_{\text{YM}} + \mathcal{L}_{\text{Dirac}} + \mathcal{L}_{\text{SCm}} + \mathcal{L}_{\text{mag}} + \mathcal{L}_{\text{buoy}} + \mathcal{L}_{\text{aether}} + \mathcal{L}_{\text{LENR}} + \mathcal{L}_{\text{KK}}$$

| 2 (YM) | Yang-Mills gauge | $m_{\text{gap}} = 1.736\;\text{GeV}$ (PAPER_1318) |

### Session 225 Phonon-Physics Upgrade: S26(3) Ramanujan Summation

> *Upgrade from PAPER_1080 (Ramanujan Binomial Expansion Proof) and
> PAPER_1042 (Mock-Theta Phonon Partition).  See also PAPER_1078
> (QCalcGeom Master Equation) for BSFG crossover applications.*

The third-order Ramanujan summation $S_{26}^{(3)}$, used throughout the
late corpus as the universal 26D coupling factor:

$$S_{26}^{(3)} = \sum_{n=0}^{\infty} \frac{(1/4)_n\,(1/2)_n\,(3/4)_n}{(n!)^3} \cdot \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

where $(a)_n = a(a+1)\cdot s(a+n-1)$ is the Pochhammer symbol.

**Binomial expansion (PAPER_1080):** The convergence proof shows:
$$R_n^{(26,3)} = \binom{4n}{n} \cdot \frac{W_{26}(n)}{(4^{4n})} \qquad \text{with}\quad W_{26}(n) = \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

This sum converges absolutely for $|[\text{SSq}]| < 1$ (satisfied by $[\text{SSq}] = 0.57$)
and reduces to the classical Ramanujan $1/\pi$ series when $[\text{SSq}] \to 0$.

**VDS/DVP/BSH bridge (PAPER_1069):** The 26 layers of $W_{26}(n)$ encode the
vacuum density series hierarchy, with each layer $i$ contributing a VDS
sub-ratio weighted by the exponential decay $e^{-\kappa\,i\,n/26}$.

**Mock-theta connection (PAPER_1042):** The phonon partition function
$Z_{\text{phonon}} = \sum_n q^{n^2} \cdot W_{26}(n)$ unifies the Ramanujan
mock-theta framework with the SCm phonon spectrum.
