"A_m550_w21p0__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, $m_A = 550$ GeV, $\Gamma_A/m_A = 21.0$% 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 $g_{H t \bar t}$.

本数据集给出了以耦合修正因子$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的两倍负对数似然观测值，该值对应的物理场景为同时存在粒子A（质量$m_A=550$ GeV，衰变宽度与质量之比$Gamma_A/m_A=21.0\%$）与粒子H（质量$m_H=850$ GeV，衰变宽度与质量之比$Gamma_H/m_H=21.0\%$）；其中相对于标准模型（Standard Model，SM）的情形对应于$g_{A tar{t}} = g_{H tar{t}} = 0$。
