Phenomenological Relationship between the Ridge and Inclusive Distributions

Abstract

A relationship between the ridge distribution in $Δη$ and the single-particle distribution in $η$ is proposed. It is then verified by use of the data from PHOBOS on both distributions. The implication seems to point to the possibility that there is no long-range longitudinal correlation. An interpretation of the phenomenological observation along that possibility is developed.
