"Figure 4 SR Distributions MA1000 MH350" of "Search for heavy neutral Higgs bosons A and H in the $\mathrm{t\bar{t}}$Z channel in proton-proton collisions at 13 TeV"

Distributions of p_T(Z) × ∆m in the SR after the fit to data with a (mA , mH) signal hypothesis of (1000, 350) GeV. The post-fit signal yields are compatible with zero events in all bins. The pre-fit signal is arbitrarily scaled and therefore omitted.

在以(m_A, m_H)=(1000, 350) GeV的信号假设对数据完成拟合后，信号区域（Signal Region，SR）内p_T(Z)与Δm的乘积分布。所有分箱内的拟合后信号产额均与零事件相容。预拟合阶段的信号经过任意标度处理，故未予展示。
