"A_m950_w5p0__H_m400_w21p0_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, $m_A = 950$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 400$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了同时存在A粒子（质量$m_A=950 ext{GeV}$，衰变宽度与质量之比$Gamma_A/m_A=5.0\%$）与H粒子（质量$m_H=400 ext{GeV}$，衰变宽度与质量之比$Gamma_H/m_H=21.0\%$）时，以耦合修正因子$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的两倍负对数似然观测值，该似然值对应标准模型（Standard Model, SM）情形，即满足$g_{A tar{t}}=g_{H tar{t}}=0$。
