"A_m650_w21p0__H_m450_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, $m_A = 650$ GeV, $\Gamma_A/m_A = 21.0$% and H, $m_H = 450$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出相对于标准模型（Standard Model, SM）的负两倍对数似然观测值，该似然值在$g_{A tar{t}} = g_{H tar{t}} = 0$时对应基准的标准模型情形；数据集对应粒子A与粒子H同时存在的物理场景，其中粒子A的质量$m_A=650 mathrm{GeV}$、衰变宽度与质量比$Gamma_A/m_A=21.0\%$，粒子H的质量$m_H=450 mathrm{GeV}$、衰变宽度与质量比$Gamma_H/m_H=5.0\%$，且该似然值为粒子A与顶夸克的耦合修正因子$g_{A tar{t}}$及粒子H与顶夸克的耦合修正因子$g_{H tar{t}}$的函数。
