"A_m1000_w21p0__H_m800_w21p0_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, $\Gamma_A/m_A = 21.0$% and H, $m_H = 800$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了A粒子（质量$m_A=1000 ext{GeV}$，衰变宽度与质量比$Gamma_A/m_A=21.0\%$）与H粒子（质量$m_H=800 ext{GeV}$，衰变宽度与质量比$Gamma_H/m_H=21.0\%$）同时存在时，相对于标准模型（Standard Model，SM）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，其中当$g_{A tar{t}}=g_{H tar{t}}=0$时，对应标准模型的基准情形。
