"A_m650_w2p0__H_m850_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, $m_A = 650$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 850$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集包含的观测值为：在同时存在质量$m_A=650 ext{GeV}$、衰变宽度与质量比$Gamma_A/m_A=2.0\%$的A粒子，以及质量$m_H=850 ext{GeV}$、衰变宽度与质量比$Gamma_H/m_H=21.0\%$的H粒子的场景下，以耦合修饰因子$g_{A tar t}$与$g_{H tar t}$为自变量的、相对于标准模型（Standard Model，SM）的两倍负对数似然观测值；该似然值对应于$g_{A tar t}=g_{H tar t}=0$的基准情形。
