Query: Poisson baseline of net-charge fluctuations in the relativistic heavy
  ion collisions   Taking doubly charged particles, positive-negative charge pair production and
the effects of volume fluctuations into account, the Poisson baseline of the
fluctuations of net-charge is studied. Within the Poisson baseline, the
cumulants of net-charge are derived. Comparing to the Skellam baseline of
net-charge, we infer that doubly charged particles broaden the distributions of
net-charge, while positive-negative charge pairs narrow the distributions.
Using the ratios of doubly charged particles and positive-negative charge pairs
from neutral resonance decays to the total positive charges from THERMINATOR 2,
the first four orders of moments and the corresponding moment products are
calculated in the Poisson baseline for Au + Au collisions at $\sqrt{s_{NN}}$ =
200 GeV at RHIC/STAR. We find that the standard deviation is mainly influenced
by the resonance decay, while the third and fourth order moments and
corresponding moment products are mainly modified and fit the data of RHIC/STAR
much better after including the effects of volume fluctuations.
