"Corr. mtrx $N_{b-jets}$ in $≥3b$" 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 $N_{b-\text{jets}}$ in the phase space with at least three b-jets. The overflow is included in the last bin.

针对至少包含3个b喷注（b-jets）的相空间区域，以$N_{b- ext{jets}}$为观测变量的测量所得归一化微分截面（normalised differential cross-section）的相关矩阵（correlation matrix）。溢出事例（overflow）被计入最后一个分箱中。
