Distribution of the MBD charge sum in minimum-bias O+O collisions at √sNN = 200 GeV (points), compared to the best fit of the MC Glauber ⊕ NBD model (red line). The lower panel shows the data-to-fit ratio, with εtrig representing the minimum-bias trigger efficiency. The dashed vertical line in the bottom panel indicates the MBD charge sum value above which the data are fully efficient.

Raw jet pT spectra in O+O collisions at √sNN = 200 GeV, after background rejection, for centrality intervals of 0–20%, 20–40%, 40–60%, 60–80%, and 0–100%. The spectra are given as counts normalized by the pTcalib bin width.

The vertical lines and boxes represent the statistical and systematic uncertainties, respectively. The boxes at unity show the systematic uncertainties for the Ncoll values.
