The 95% CL observed and expected limits on the branching fraction B(H $\rightarrow \Psi\Psi$) for photon portal, assuming $(\xi_{\omega}$, $\xi_{\Lambda}) = (1, 1)$ and 15 GeV LLP mass.

在假设(ξ_ω, ξ_Λ)=(1,1)且长寿命粒子（Long-Lived Particle, LLP）质量为15 GeV的条件下，针对光子门户（photon portal）模型，希格斯玻色子H衰变为双Ψ的衰变分支比B(H→ΨΨ)所对应的95%置信限（Confidence Limit, CL）观测值与预期值。
