|
||
**Spin structure of mesons:**
|
||
- Spin-0: quark spins anti-aligned (S_q = 0) + L = 0 → J = 0
|
||
- Spin-1: quark spins aligned (S_q = 1) + L = 0 → J = 1
|
||
- Higher spins: orbital angular momentum L > 0 added to S_q
|
||
|
||

|
||
| Λ_b⁰ | udb | 1/2 | 5619.6 |
|
||
|
||
**Spin structure of baryons:**
|
||
- Spin-1/2: three quark spins combine to S_q = 1/2 + L = 0 → J = 1/2
|
||
- Spin-3/2: three quark spins combine to S_q = 3/2 + L = 0 → J = 3/2
|
||
- The proton and neutron are the only stable baryons (neutron unstable outside nucleus)

## Spin Correlation and Entanglement (LHC Data)
|
||
|
||
### Top quark spin correlation matrix (CMS/ATLAS 2024)
|
||
The spin correlation matrix C for a tt̄ pair is defined as:
|
||
|
||
```
|
||
C_{ij} = (σ_{ij} - δ_{ij}) / 3
|
||
```
|
||
|
||
where σ_{ij} = 4 ⟨s_i ⊗ s_j⟩ is the normalized spin correlation. The entanglement condition is:
|
||
|
||
```
|
||
|Tr(C)| > 1 (PPT criterion for entanglement)
|
||
```
|
||
|
||
| Observable | SM Prediction | ATLAS/CMS Measurement |
|
||
|-----------|---------------|----------------------|
|
||
| ΔΦ_ℓℓ (lepton angle difference) | ~2.9 rad | 2.87 ± 0.05 rad |
|
||
| A_ΔΦ (asymmetry) | 0.42 | 0.41 ± 0.03 |
|
||
| C_{kk} (longitudinal correlation) | -0.31 | -0.29 ± 0.04 |
|
||
| C_{rr} (transverse correlation) | +0.18 | +0.16 ± 0.04 |
|
||
|
||
**Result: entanglement confirmed at >5σ.**

## For Compression: Spin as Information Capacity
|
||
|
||
| Spin s | Number of spin states (2s + 1) | Information per particle (bits) |
|
||
|--------|-------------------------------|----------------------------------|
|
||
| 0 | 1 | 0 |
|
||
| 1/2 | 2 | 1 |
|
||
| 1 | 3 | log₂(3) ≈ 1.58 |
|
||
| 3/2 | 4 | 2 |
|
||
| 2 | 5 | log₂(5) ≈ 2.32 |
|
||
|
||
A spin-1/2 particle is a **qubit** (2 states = 1 bit).
|
||
The Standard Model fermions are 48 qubits (if distinguishable).
|
||
The total Hilbert space dimension of SM particles: 2⁴⁸ × 3¹² × 1¹ ≈ 10²⁰.
