Title: Multiplicity correlations between neutral and charged pions from charged multiplicity distributions
Abstract: It is shown that for several simple possibilities of distributing charge between pions (the so-called π, ϵ and ϱ models) the (πOπch) multiplicity correlations can be expressed directly in terms of the charged multiplicity distributions. Each of the models can then be tested experimentally, irrespectively of the unknown total multiplicity distribution.
