"A_m800_w5p0__H_m500_w2p0_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, $m_A = 800$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 500$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

该数据集所包含的观测值为：以标准模型（Standard Model, SM）为基准的两倍负对数似然值，该基准对应于耦合修正因子$g_{A tar{t}} = g_{H tar{t}} = 0$的情形；该观测值针对同时存在A粒子（质量$m_A=800 ext{GeV}$，衰变宽度与质量比$Gamma_A/m_A=5.0\%$）与H粒子（质量$m_H=500 ext{GeV}$，衰变宽度与质量比$Gamma_H/m_H=2.0\%$）的物理场景，且为耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$的函数。
