"A_m400_w5p0__H_m450_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, $m_A = 400$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 450$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集包含以下观测结果：针对标准模型（Standard Model, SM）中$g_{A tar{t}} = g_{H tar{t}} = 0$的基准情形，当A粒子（质量$m_A=400 ext{GeV}$，衰变宽度与质量比$Gamma_A/m_A=5.0\%$）与H粒子（质量$m_H=450 ext{GeV}$，衰变宽度与质量比$Gamma_H/m_H=2.0\%$）同时存在时，其二倍负对数似然的观测值；该观测值以耦合修饰因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量，呈现对应的函数关系。
