"A_m365_w2p0__H_m365_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, $m_A = 365$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 365$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了以耦合修正参数$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的观测值：该观测值为同时存在A粒子（质量$m_A=365$ GeV，衰变宽度与质量比值$Gamma_A/m_A=2.0\%$）与H粒子（质量$m_H=365$ GeV，衰变宽度与质量比值$Gamma_H/m_H=5.0\%$）时，对应于$g_{A tar{t}}=g_{H tar{t}}=0$情形的标准模型（Standard Model, SM）相对两倍负对数似然值。
