资源简介:
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, $m_A = 800$ GeV, $\Gamma_A/m_A = 2.0$% and H, $m_H = 1000$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.

本数据集提供的观测值为:以耦合修正系数(coupling modifiers)$g_{A tar{t}}$和$g_{H tar{t}}$为自变量的函数,其函数值为新粒子A(质量$m_A=800$ GeV,$Gamma_A/m_A=2.0\%$)与H(质量$m_H=1000$ GeV,$Gamma_H/m_H=2.0\%$)同时存在时,相对于标准模型(Standard Model, SM)的两倍负对数似然值,且该似然值对应$g_{A tar{t}}=g_{H tar{t}}=0$的情形。
