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, $m_A = 500$ GeV, $\Gamma_A/m_A = 5.0$% and H, $m_H = 400$ GeV, $\Gamma_H/m_H = 2.0$% as a function of the coupling modifiers $g_{A t \bar t}$ and $g_{H t \bar t}$.
本数据集给出了粒子A与粒子H同时存在场景下,以耦合修正因子$g_{A tar{t}}$与$g_{H tar{t}}$为自变量的观测值;该观测值为针对标准模型(Standard Model, SM)的两倍负对数似然值,对应耦合修正因子$g_{A tar{t}}=g_{H tar{t}}=0$的基准情形;其中粒子A的质量$m_A=500$ GeV,衰变宽度与质量之比$Gamma_A/m_A=5.0\%$,粒子H的质量$m_H=400$ GeV,衰变宽度与质量之比$Gamma_H/m_H=2.0\%$
