Right-left multiplicities and the Pomeranchuk singularity

Abstract
The left-right multiplicity cross sections for producing nL particles in the left c.m. hemisphere and nR particles in the right c.m. hemisphere are discussed. It is found that these distributions provide a set of quantitative tests for the existence of a nonfactorizable part of the Pomeranchuk singularity. It is also found that the multiplicity distribution in a single hemisphere is a more sensitive test of the Wilson two-component idea than is the total multiplicity distribution. New NAL data show evidence for such a two-component structure.
