"A_m650_w2p0__H_m800_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, $m_A = 650$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 800$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了同时存在质量为650 GeV、衰变宽度与质量之比为2.0%的A粒子，以及质量为800 GeV、衰变宽度与质量之比为2.0%的H粒子时，相对于标准模型（Standard Model, SM）的两倍负对数似然观测值；该观测值对应于$g_{A tar{t}} = g_{H tar{t}} = 0$的情形，且其取值以耦合修饰因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量的函数形式呈现。
