Key Relations
[L_m, L_n] = (m-n)L_{m+n} + c/12 m(m²-1)δ
⟨O(x)O(0)⟩ = C/|x|^{2Δ}
h = (Δ+s)/2, h̄ = (Δ-s)/2
State-operator: each primary O(0)|0⟩ = |Δ,s⟩ gives a state in radial quantization on S^{d-1}.
L_0|Δ⟩ = Δ|Δ⟩
L_n|Δ⟩ = 0, n > 0
Unitarity bound: Δ ≥ (d-2)/2 for scalars. Violating this is excluded by the conformal bootstrap.
