Enhancement of Compton Scattering by an Effective Coupling Constant

Abstract

A robust thermodynamic argument shows that a small reduction of the effective coupling constant $\alpha$ of QED greatly enhances the Compton scattering cross section and that the Thomson scattering length is connected to a fundamental scale $\lambda$. A discussion provides a possible quantum interpretation of this enormous sensitivity to changes in the effective coupling constant $\alpha$.
