"A_m750_w2p0__H_m750_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, $m_A = 750$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 750$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

针对同时存在质量$m_A=750 mathrm{GeV}$、宽度与质量比$Gamma_A/m_A=2.0\%$的A粒子，与质量$m_H=750 mathrm{GeV}$、宽度与质量比$Gamma_H/m_H=5.0\%$的H粒子的物理场景，以耦合修正因子$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的观测值，即为对应标准模型（Standard Model, SM）下$g_{A tar{t}}=g_{H tar{t}}=0$情形的两倍负对数似然值。
