"A_m365_w21p0__H_m750_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, $m_A = 365$ GeV, $\Gamma_A/m_A = 21.0$% and H, $m_H = 750$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集包含了同时存在质量为365 GeV、宽度与质量之比$Gamma_A/m_A=21.0\%$的粒子A，以及质量为750 GeV、宽度与质量之比$Gamma_H/m_H=2.0\%$的粒子H时，相对于标准模型（Standard Model，SM）且对应于$g_{A tar t}=g_{H tar t}=0$情形的两倍负对数似然观测值，该观测值以耦合修正因子$g_{A tar t}$与$g_{H tar t}$为函数自变量。
