"A_m500_w5p0__H_m700_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, $m_A = 500$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 700$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出以耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量的观测值，对应粒子A与粒子H同时存在的情形：粒子A的质量$m_A=500 ext{GeV}$，衰变宽度与质量之比$Gamma_A/m_A=5.0\%$；粒子H的质量$m_H=700 ext{GeV}$，衰变宽度与质量之比$Gamma_H/m_H=5.0\%$。该观测值为相对于标准模型（Standard Model，SM）的两倍负对数似然值，其基准情形为$g_{A tar{t}}=g_{H tar{t}}=0$。
