"A_m365_w21p0__H_m500_w5p0_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, $m_H = 500$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了以标准模型（Standard Model, SM，对应$g_{A tar{t}}=g_{H tar{t}}=0$）为基准的两倍负对数似然观测值，该观测值对应同时存在质量$m_A=365 mathrm{GeV}$、宽度与质量比$Gamma_A/m_A=21.0\%$的A粒子，以及质量$m_H=500 mathrm{GeV}$、宽度与质量比$Gamma_H/m_H=5.0\%$的H粒子的物理场景，且该观测值以耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量。
