  The event-by-event charge fluctuation measurements are proposed to provide
the signature of quark-gluon plasma (QGP) in heavy-ion collisions. Measure of
dynamical charge fluctuations is expected to carry information of initial
fractional charge of the QGP phase at the final state. We propose the higher
order charge fluctuation measurement to study the QGP signal in heavy-ion
collisions. This higher order charge fluctuation observable can amplify the
signature of QGP. Also, the SMASH model is used to study the behavior of these
observable in heavy-ion collisions at center of mass energies accessible in the
STAR beam energy scan program.
