"A_m750_w5p0__H_m500_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, $\Gamma_A/m_A = 5.0$% and H, $m_H = 500$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出针对如下场景的两倍负对数似然观测值：该值以标准模型（Standard Model, SM）为参照基准，对应耦合修正因子$g_{A tar{t}}=g_{H tar{t}}=0$的情形；场景为A粒子与H粒子同时存在，其中A粒子质量$m_A=750$吉电子伏特（GeV），衰变宽度与质量之比$Gamma_A/m_A=5.0\%$，H粒子质量$m_H=500$吉电子伏特（GeV），衰变宽度与质量之比$Gamma_H/m_H=5.0\%$。上述两倍负对数似然值为耦合修正因子（coupling modifiers）$g_{A tar{t}}$与$g_{H tar{t}}$的函数。
