"A_m1000_w21p0__H_m1000_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, $m_A = 1000$ GeV, $\Gamma_A/m_A = 21.0$% and H, $m_H = 1000$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

观测得到的、相对于标准模型（Standard Model，SM）的两倍负对数似然值（对应于$g_{A tar{t}} = g_{H tar{t}} = 0$的基准情形），以耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量，其对应的物理场景为同时存在粒子A（质量$m_A=1000$ GeV，衰变宽度与质量比$Gamma_A/m_A=21.0\%$）与粒子H（质量$m_H=1000$ GeV，衰变宽度与质量比$Gamma_H/m_H=5.0\%$）。
