"A_m500_w21p0__H_m500_w5p0_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, $\Gamma_A/m_A = 21.0$% and H, $m_H = 500$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集包含的观测值为：针对标准模型（Standard Model，SM）、满足$g_{A tar{t}} = g_{H tar{t}} = 0$条件的两倍负对数似然值；该观测值对应A粒子与H粒子同时存在的物理场景，其中A粒子的质量$m_A=500$ GeV、$Gamma_A/m_A=21.0\%$，H粒子的质量$m_H=500$ GeV、$Gamma_H/m_H=5.0\%$；且该观测值以耦合修饰因子（coupling modifiers）$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的函数。
