Abstract

Contact terms - similar to those dominating the γγ → π+π- cross section for Wγγ ≲ 1 GeV - are found to be relevant when dealing with σ((γγ → Δp+Δp → NNπ) near threshold. This cross section is predicted to be much larger than observed for γγ → pp. From their study and comparison new features of hadron dynamics could be learned. © 1984.
