* ABSTRACT

In this work, the charge transfer fluctuation which was previously used
for $pp$ collisions is proposed for relativistic heavy-ion collisions as
a QGP probe. We propose the appearance of a local minimum at
midrapidity for the charge transfer fluctuation as a signal for a QGP.
Within a two-component neutral cluster model, we demonstrate that
the charge transfer fluctuation can detect the presence of a QGP
as well as the size of the QGP in the rapidity space. We also show
that the forward-backward correlation of multiplicity can be a
similarly good measure of the presence of a QGP. Further, we show
that the previously proposed net charge fluctuation is sensitive to
the existence of the second phase only if the QGP phase occupies
a large portion of the available rapidity space.
