"Corr. mtrx $m(bb^{add})$ in $≥4b$" of "Measurement of $t\bar{t}$ production in association with additional $b$-jets in the $e\mu$ final state in proton-proton collisions at $\sqrt{s}$=13 TeV with the ATLAS detector"

The correlation matrix for the measured normalised differential cross-section in terms of $m(bb^{\text{add}})$ in the phase space with at least four b-jets. The overflow is included in the last bin.

本相关矩阵对应相空间内至少包含4个b喷注的事件样本中，以bb附加对不变质量$m(bb^{ ext{add}})$为变量的测量归一化微分截面，且溢出事件被纳入最后一个分箱中。
