"A_m450_w5p0__H_m900_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, $m_A = 450$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 900$ GeV, $\Gamma_H/m_H = 21.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集给出了同时存在A粒子与H粒子时，相对于标准模型（Standard Model, SM）的两倍负对数似然（negative log-likelihood）观测值。其中A粒子的质量为450吉电子伏特（GeV），衰变宽度与质量之比Γ_A/m_A=5.0%；H粒子的质量为900吉电子伏特（GeV），衰变宽度与质量之比Γ_H/m_H=21.0%。该似然值以耦合修正参数g_{A t ar t}和g_{H t ar t}为自变量变化，其基准情形对应g_{A t ar t}=g_{H t ar t}=0。
