"A_m500_w5p0__H_m950_w21p0_2dnll" of "Search for heavy pseudoscalar and scalar bosons decaying to a top quark pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Observed values of twice the negative log-likelihood with respect to the SM (corresponding to $g_{A t \bar t} = g_{H t \bar t} = 0$) for the simultaneous presence of A, $m_A = 500$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 950$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

针对同时存在A粒子（质量$m_A=500 ext{GeV}$、$Gamma_A/m_A=5.0\%$）与H粒子（质量$m_H=950 ext{GeV}$、$Gamma_H/m_H=21.0\%$）的观测场景，本数据集给出了相对于标准模型（Standard Model，SM）的两倍负对数似然观测值；其中当耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$均为0时对应标准模型基准情形，该似然值以这两个耦合修正因子为自变量函数。
