"A_m850_w5p0__H_m1000_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, $m_A = 850$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 1000$ 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：在A粒子（质量$m_A=850$ GeV，$Gamma_A/m_A=5.0\%$）与H粒子（质量$m_H=1000$ GeV，$Gamma_H/m_H=5.0\%$）同时存在的场景下，以耦合修正参数$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的、相对于标准模型（Standard Model，SM）的两倍负对数似然值，其中该似然值的参考基准对应$g_{A tar{t}}=g_{H tar{t}}=0$。
