Two-Particle Distributions and the Nature of the Pomeranchuk Singularity

Abstract

We propose the measurement of reactions of the type $p_1+p_2\to q_1+q_2+$ anything at high energy in the region in which the produced particles $q_1$ and $q_2$ can be regarded as "fragments" of the incident particles $p_1$ and $p_2$, respectively. Dependence of the cross section on the angle between transverse parts of the vectors ${\overrightarrow{\mathrm{q}}}_1$ and ${\overrightarrow{\mathrm{q}}}_2$ would indicate that the Pomeranchuk singularity contains Regge-cut contributions.
