Description
Multiplicity correlations between distant forward and backward
(FB) rapidity regions in relativistic heavy-ion collisions are examined
in a superposition framework. Our three-stage approach incorporates
the fluctuations of parton production in the early phase (modeled
with the Glauber simulations), the effects of intermediate hydrodynamic
evolution, and fluctuations in the production mechanism
at freeze-out. Characterization of the three stages with several
parameters leads to very simple relations between the statistical moments
of the distributions of the initial sources and of the produced particles.
Our study has a direct relevance for the interpretation of the upcoming
results for the FB correlations at the LHC, allowing for an assessment of
the statistical features of the state formed in the earliest stage of the reaction.
