"A_m600_w2p0__H_m900_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, $m_A = 600$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 900$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出同时存在粒子A（质量$m_A=600 ext{GeV}$，衰变宽度与质量比值$Gamma_A/m_A=2.0\%$）与粒子H（质量$m_H=900 ext{GeV}$，衰变宽度与质量比值$Gamma_H/m_H=5.0\%$）时，以耦合修饰因子（coupling modifiers）$g_{A tar{t}}$与$g_{H tar{t}}$为自变量的观测值，该观测值为以标准模型（Standard Model, SM）为基准的两倍负对数似然，且对应$g_{A tar{t}}=g_{H tar{t}}=0$的参考情形。
