"A_m365_w21p0__H_m550_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, $m_A = 365$ GeV, $\Gamma_A/m_A = 21.0$% and H, $m_H = 550$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集提供了以耦合修正因子$g_{A t ar t}$与$g_{H t ar t}$为自变量的观测两倍负对数似然值，该值对应A粒子（质量$m_A=365$吉电子伏特，衰变宽度与质量之比$Gamma_A/m_A=21.0\%$）与H粒子（质量$m_H=550$吉电子伏特，衰变宽度与质量之比$Gamma_H/m_H=21.0\%$）同时存在的场景，且以标准模型（Standard Model，SM）为基准，其基准条件为$g_{A t ar t}=g_{H t ar t}=0$。
