Factorization Theorems for High Energy nn, gamma p and gamma gamma Scattering

M. M. Block

The robustness of the factorization theorem for total cross sections, ${\sigma }_{nn}/{\sigma }_{\gamma p}={\sigma }_{\gamma p}/{\sigma }_{\gamma \gamma }$, originally proved by Block and Kaidalov\cite{bk} for $nn$ (the even portion of…
