Singlet cross section and the tensor interaction in $\overline{\mathrm{p}}\mathrm{p}\to \bar{\Lambda }\Lambda$

Abstract

In this short paper, we demonstrate using irreducible tensorial techniques and in a model-independent way, why tensor interactions and also orbital-angular momentum-changing vector interactions are absent in the singlet unpolarized differential cross section for the reaction $\overline{\mathrm{p}}\mathrm{p}\to \bar{\Lambda }\Lambda$.
