"A_m1000_w5p0__H_m550_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, $m_A = 1000$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 550$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

以耦合修正因子$g_{A t ar{t}}$与$g_{H t ar{t}}$为自变量的函数，针对同时存在A粒子（$m_A=1000 ext{GeV}$，$Gamma_A/m_A=5.0\%$）与H粒子（$m_H=550 ext{GeV}$，$Gamma_H/m_H=5.0\%$）的物理场景，给出其相对于标准模型（Standard Model，SM）的两倍负对数似然观测值；其中基准情形对应$g_{A t ar{t}}=g_{H t ar{t}}=0$。
