Abstract：
The dependencies of all suggested measures for charge fluctuation on the size of rapidity window are compared using the nucleonic and nuclear collision models—PYTHIA and RQMD. It is found that such dependency is model dependent. However, the charge correlations have the best measure for the effects of global charge conservation and short-range rapidity correlation and is therefore recommended.
