"A_m450_w2p0__H_m900_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, $m_A = 450$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 900$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了以耦合修饰因子（coupling modifiers）$g_{A tar{t}}$与$g_{H tar{t}}$为函数自变量的观测值，该观测值为针对同时存在粒子A（质量$m_A=450$ GeV，宽度与质量比$Gamma_A/m_A=2.0\%$）与粒子H（质量$m_H=900$ GeV，宽度与质量比$Gamma_H/m_H=21.0\%$）的物理场景下，相对于标准模型（Standard Model，SM）的负两倍对数似然；其中当$g_{A tar{t}}=g_{H tar{t}}=0$时，该似然值即对应标准模型的基准情形。
