"Fig. 6b" 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"

Distribution of the largest reduced invariant mass of any displaced vertex, $m_{\mathrm{DV}}^{\mathrm{red}}$, in the near 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.

近信号区域内任意位移顶点的最大约化不变质量$m_{mathrm{DV}}^{mathrm{red}}$的分布。数据中最高$m_{mathrm{DV}}^{mathrm{red}}$箱未观测到任何事例。采用数据驱动传递因子方法得到的本底预测结果已给出，同时叠加了用于演示的示例信号基准模型——即发生$lambda'_{211}$衰变的希格斯ino对产生过程，其质量$m=1500, ext{GeV}$，寿命$ au=0.1, ext{ns}$——以供说明。下方子图展示了观测数据与总本底预测值的比值。
