"A_m400_w2p0__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, $m_A = 400$ GeV, $\Gamma_A/m_A = 2.0$% 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 $g_{H t \bar t}$.

针对A粒子（质量$m_A=400 ext{GeV}$，$Gamma_A/m_A=2.0\%$）与H粒子（质量$m_H=1000 ext{GeV}$，$Gamma_H/m_H=5.0\%$）同时存在的情形，本数据集给出以标准模型（Standard Model, SM）下$g_{A tar{t}}=g_{H tar{t}}=0$为参考基准的两倍负对数似然观测值，该观测值为耦合修正参数$g_{A tar{t}}$与$g_{H tar{t}}$的函数。
