Two Photon Couplings of Hybrid Mesons

A new formalism is developed for the two photon production of hybrid mesons via intermediate hadronic decays. In an adiabatic and non–relativistic context with spin 1 QQ̄ pair creation we obtain the first absolute estimates of unmixed hybrid production strengths to be small ( ∼ 0.03 − 3 eV) in relation to experimental meson widths (∼ 0.1 − 5 keV).
