"A_m365_w21p0__H_m365_w2p0_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, $\Gamma_A/m_A = 21.0$% and H, $m_H = 365$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集提供了如下场景下的两倍负对数似然观测值：当A粒子与H粒子同时存在时，其中A粒子的质量$m_A=365 ext{GeV}$、宽度与质量之比$Gamma_A/m_A=21.0\%$，H粒子的质量$m_H=365 ext{GeV}$、宽度与质量之比$Gamma_H/m_H=2.0\%$；该观测值为相对于标准模型（Standard Model, SM，即满足$g_{A tar{t}}=g_{H tar{t}}=0$的情形）的结果，且其随耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$的取值变化而变化。
