We consider a simple model of net charge fluctuations in high-energy nucleus-nucleus collisions inspired by the string picture of hadronic interactions. It is found that in this model the so-called D measure of the net charge fluctuations used by Jeon and Koch depends only on the parameters characterizing the charge fluctuations inside a string and does not depend on the event-by-event fluctuations of the number of strings.

Abstract
We consider a simple model of net charge fluctuations in high-energy nucleus-nucleus collisions inspired by the string picture of hadronic interactions. It is found that in this model the so-called D measure of the net charge fluctuations used by Jeon and Koch depends only on the parameters characterizing the charge fluctuations inside a string and does not depend on the event-by-event fluctuations of the number of strings.
