Figure Caption
pT spectra of Xi*0 in Pb-Pb collisions in 0-10%(Central), 10-40%(Semi-Central), 40-80%(Peripheral) and 0-80% centrality classes.
Dashed lines are Boltzmann fit which is used to obtain the integrated yield. EPOS v3.107 predictions are shown as filled area.
Bars are statistical uncertainties, boxes are systematics.
