"Fig. 6a" of "Search for massive, long-lived particles in events with displaced vertices and displaced muons in $pp$ collisions at $\sqrt{s}=13.6$ TeV with the ATLAS experiment"

Distributions of the largest reduced invariant mass of any displaced vertex, $m_{\mathrm{DV}}^{\mathrm{red}}$, in the far signal region. No events are observed in data in the highest $m_{\mathrm{DV}}^{\mathrm{red}}$ bin. The background predictions derived using the data-driven transfer factor method are shown, along with an example signal benchmark (higgsino pair production with $\lambda'_{211}$ decays, $m = 1500\,\text{GeV}$ and $\tau = 0.1\,\text{ns}$) overlaid for illustration. The lower panels show the ratio of observed data to the total background prediction.
