"A_m950_w21p0__H_m1000_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, $m_A = 950$ GeV, $\Gamma_A/m_A = 21.0$% and H, $m_H = 1000$ GeV, $\Gamma_H/m_H = 5.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

该数据集给出了同时存在质量为950 GeV、衰变宽度与质量比为21.0%的A粒子，以及质量为1000 GeV、衰变宽度与质量比为5.0%的H粒子时，以耦合修饰因子$g_{A t ar{t}}$和$g_{H t ar{t}}$为自变量的观测值——该值为相对于标准模型（Standard Model，SM）的两倍负对数似然值，其中标准模型对应$g_{A t ar{t}}=g_{H t ar{t}}=0$的情形。
