Explanation — context & formalism

P15 — Hadron Spectrum: Regge + Charmonium

Problem

Extend P13 (Regge slope, string breaking) to the full measured hadron spectrum. Two regimes:

Method

Regge (versant A): Test M² = 2πσ(2n + L) against ρ meson radial (n) and orbital (L=J) excitations.

Charmonium (versant B): Solve −(ℏ²/2μ)∇² − k/r + σr for mc = 1.84 GeV, k = 0.52 GeV/fm. The absolute constant V₀ cancels in level spacings.
