Description
Several excesses around 95 GeV hint at an additional light scalar beyond the Standard Model. We examine the CEPC's capability to test this hypothesis via the Higgsstrahlung channel $e^+e^-\to ZS$ ($Z\to\mu^+\mu^-$, $S\to\tau^+\tau^-/b\bar{b}$). Our results show that a 210 GeV CEPC run with deep neural networks robustly probes the 95 GeV excess, covering large model parameter spaces. We also discuss future hadron colliders (HL-LHC, HE-LHC, FCC-hh, SppC) for contrast, and use representative models (MDM, Type-I 2HDM, flipped N2HDM, NMSSM) to illustrate these colliders' reach.
