Charge correlations in heavy ion collisions

Abstract

When hot quark gluon plasma expands and cools down after an heavy ion collision, charge conservation leads to non-trivial correlations between the charge densities at different rapidities. If these correlations can be measured, they will provide information about dynamical properties of quark gluon plasma.
