We report the first result of the net-proton cumulants and cumulant ratios in FXT Au+Au collisions at 4.5 GeV measured by the STAR experiment.

The results show that the net-proton cumulants (C1-C4) increase as function of the and show saturation/suppression at central collisions.

Cumulant ratios are all above unity and decrease from mid-central to central.
