Computing masses, spins and charges

Note. This module presents the canonical formula m = √σχ 𝒮: 89 masses at 0.13 % median (226 states at 1.43 %). The historical formulas (empirical form, Ωts operator) are described at the end of the module, as archives; the Koide relation is explained (the article).

You now have the tools (knots, invariants, Chern–Simons). Let us see how they produce a concrete particle spectrum — masses, spins, charges, and even the nucleon as a link.

1. The canonical mass formula

The central formula of the mass computation reads:

$$\boxed{m \;=\; \sqrt{\sigma_\chi}\;\times\;\mathcal{S}}$$

A single dimensionful scale, $\sqrt{\sigma_\chi} = 418{,}47$ MeV — the tension of the $\chi$ string, read off the hadronic Regge slope — times a pure number $\mathcal{S}$ set by the particle's topological class. Each class has its sector law:

Global score: 89 states at 0.13 % median; the 226-state extension holds at 1.43 %.

2. One scale, sector laws

Why not a single formula applied to every knot? Because a particle's three attributes are not carried by the same structure. The “$\sigma_\chi$ prevails” principle:

$$\Delta M^2_{\rm Regge} = 2\pi\sigma_\chi\,, \qquad \Delta M^2_{V\!-\!P} = \pi\sigma_\chi = 0{,}5501\ \mathrm{GeV}^2$$

the knot configuration carries the spin (braid arity) and the charge ($Q = \sum\chi + Lk$); the mass follows the law of its sector — the way the object grips the $\chi$ string. All the laws share the same scale: the $\mathcal{S}$ factors are pure numbers ($\sqrt{2}$, $\pi/12$, $3/4$, integer ratios…).

It is the same move as in atomic physics: a single scale constant (the rydberg), and level laws specific to each situation.

3. What is calibrated, what is derived

The scale is calibrated — once, globally. And it is doubly constrained: the leptons (through Koide) and the octet base demand the same value to $7\times10^{-5}$:

$$\sqrt{\sigma_\chi} = 418{,}47\ \text{MeV}$$

The full spectrum rests on 10 global parameters, 9 of them for the mass sector — never one parameter per particle. And many links are derived: Koide's $\sqrt{2}$ amplitude (quantum-dimension theorem), the $\pi\sigma_\chi$ half-turn, the ×3 generation step (the $Z_3$ triality of the trefoil), the electroweak scale $v$ (to 28 ppm).

No further parameter is adjusted afterwards: every mass below is an output of the same machinery.

4. Two concrete examples

The proton (octet base)

The nucleon is the base of the baryon sector: its factor $\mathcal{S}_{\rm octet}$ is built on the Regge base, with no proton-specific parameter:

$$m_p = \sqrt{\sigma_\chi}\times\mathcal{S}_{\rm octet} = 938{,}2\ \text{MeV}$$

Measured: 938.27 MeV — a 0.0 % deviation.

The universal half-turn: $K^*$ vs $K$

The vector meson $K^*$ is the $K$ meson whose ribbon has flipped by half a turn. The cost is the quantum $\pi\sigma_\chi$:

$$m_{K^*}^2 - m_K^2 = 0{,}551\ \text{GeV}^2 \;\approx\; \pi\sigma_\chi = 0{,}5501\ \text{GeV}^2$$

Deviation: 0.2 %. The same half-turn links every vector–pseudoscalar pair, from $\pi/\rho$ to $B_s/B_s^*$ (0.7 % median), with no parameter at all.

5. The spin rules

Spin is not computed: it is read off the object's braid structure, through three facts:

Three typical readings:

StructureSpin $s$Example
single torus knot ($3_1$)$1/2$electron, muon, tau
knot + mirror pair ($K + \bar{K}$: a meson)$0$ or $1$$\pi$ (0), $\rho$ (1) — split by the half-turn
3-component link ($\tfrac12\otimes1\otimes1$)$1/2$ or $3/2$proton (octet), $\Delta$ (decuplet)

Orbital excitations (P and D waves) add $L$: the heavy-spectrum bands follow closed rules, derived in the monograph.

6. The electric charge

For a link $L = K_1 \cup \cdots \cup K_n$ with several components, the total charge reads:

$$\boxed{Q(L) = \sum_{i=1}^{n} \chi(K_i) + Lk(L)}$$

where:

$\sigma(K)$ is the curvature saturation (= $\pm 1$ for toric knots, 0 for amphicheiral ones), and $b(K)$ is the braid index. The result $Q \in \mathbb{Z}$ is a theorem — charge quantization is derived, not postulated.

7. The nucleon: a $3_1 + 7_2 + \bar{7}_2$ link

The proton and the neutron are, in TQNT, one and the same link: a trefoil ($3_1$) and a mirror pair of twist knots ($7_2 + \bar{7}_2$ — the mirror of $7_2$, of opposite chirality: their topological charges $+3$ and $-3$ compensate). The invariants:

Component$c_J$$U_{EM}$$b$$\chi$
$3_1$ (trefoil)3.39.02$-2$
$7_2$ (twist)8.133.83$+3$
$\bar{7}_2$ (mirror twist)8.133.83$-3$
Total19.576.7—$-2$

Charge: $Q = \sum \chi + Lk = -2 + Lk$.

8. The n–p mass difference = 1.293 MeV

The optimal linking is $Lk_{\rm opt} = +3$ (the proton, minimum energy). Any deviation from the optimum costs energy following a harmonic potential:

$$E_{\rm tension} = \beta\, (\Delta Lk)^2\, \langle\sqrt{c_J^{(i)}\, c_J^{(j)}}\rangle$$

For the neutron, $\Delta Lk = -1$, hence:

$$E_{\rm tension}({\rm neutron}) = 0{,}210\, \text{MeV} \cdot 1 \cdot 6{,}15 = 1{,}293\, \text{MeV}$$

This tension is exactly the measured mass difference:

$$m_n - m_p = 1{,}293\, \text{MeV} \quad \text{(exp.)}$$

No parameter adjusted for this result (apart from $\beta = 0{,}210$ MeV, one of the 10 global parameters, calibrated once and for all — its mechanism, fluxoid trapping, is identified).

9. Historical note: the archived formulas

Early versions of the theory used a single formula applied to every knot: the empirical form $m = \alpha_0\, U_{EM}\, c_J^{3{,}55}$ (one calibrated scale, the knot's intrinsic EM energy, its topological complexity), then the $\Omega_{ts}$ operator derived from the Chern–Simons flow. They reproduced 118/122 masses (0.68 % median) — but that engine rested on the catalogue curves, 14 of 19 of which turned out to be topologically wrong, and on too much assignment freedom. Those chapters are archived in the monograph.

The canonical formula $m = \sqrt{\sigma_\chi}\times\mathcal{S}$ replaces them: fewer parameters, better accuracy, and sector laws several links of which are theorems (the $\pi\sigma_\chi$ half-turn, the Y-junction triality, Koide's $\sqrt{2}$ amplitude). It is the one presented throughout the rest of the site.

Key takeaways

Mass reads $m = \sqrt{\sigma_\chi}\times\mathcal{S}$: a single scale (418.47 MeV, the tension of the $\chi$ string) and a pure number set by the topological class — 89 masses at 0.13 % median. Spin is read off the braid ($4\pi$ parity, inverse Regge); charge is $Q = \sum\chi + Lk$, integer by theorem. The nucleon is the $3_1 + 7_2 + \bar{7}_2$ link, and the $n - p = 1{,}293$ MeV mass difference comes out of the linking alone.

End-of-module quiz

Four questions on computing the particle spectrum.

1. What is the structure of the canonical mass formula?

There you go. The first option is the historical, archived form — it is described at the end of the module.

2. Where does the proton's spin $1/2$ come from?

Exactly. And the same composition gives $3/2$ for the decuplet ($\Delta$, $\Omega^-$) — same content, different coupling.

3. What is the electric-charge formula of a link in TQNT?

Right. And the result is necessarily an integer, which proves charge quantization.

4. For the nucleon ($3_1 + 7_2 + \bar{7}_2$ link), why does the proton have $Q = +1$ and the neutron $Q = 0$?

Exactly. And it is the same topological structure, with a single parameter ($Lk$) distinguishing them — which makes the prediction of their mass difference immediate.
