During this presentation, I will provide a concise overview of the CEPC's recent advancements in SUSY, dark matter, and dark sector research.
The Circular Electron-Positron Collider (CEPC) is expected to operate at center-of-mass energies of 240–250 GeV to produce the Standard Model Higgs boson and make precise measurements. This will also allow for the production of additional lighter scalars. Following the excesses seen at the LHC around $m_S \approx 95$ GeV, we explore the feasibility of a singlet scalar $S$ in a 2HDM+$S$...
In light of the hints for a new scalar at the LHC at 95 GeV, I present an analysis of low-mass WW searches. In particular, a scalar SU(2) triplet is a possible candidate. In this case, one predicts a charged Higgs boson, nearly degenerate in mass, whose properties could be studied with high precision at a future e+e- collider like CEPC.
We discuss the phenomenology of light Higgs bosons at the CEPC. We focus on a Higgs boson at $\sim 95$ GeV, as suggested by recent ATLAS and CMS searches. Such a scenario can be tested in two ways at CEPC: 1) via precision measurements of the $h_{125}$; 2) via direct production of the $h_{95}$. We demonstrate that these measurements are crucial to determine the characteristics of the BSM Higgs sector.
