"A_m600_w5p0__H_m1000_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, $m_A = 600$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 1000$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集提供了以耦合修饰量$g_{A tar t}$与$g_{H tar t}$为自变量的观测值，该观测值为同时存在粒子A（质量$m_A=600$ GeV，衰变宽度与质量之比$Gamma_A/m_A=5.0\%$）与粒子H（质量$m_H=1000$ GeV，衰变宽度与质量之比$Gamma_H/m_H=21.0\%$）时，相对于标准模型（Standard Model, SM）的两倍负对数似然，其中标准模型对应$g_{A tar t}=g_{H tar t}=0$的情形。
