Search for Light Neutral Scalar in the Georgi-Machacek Model with Forward Detectors at the LHC
Yuanqian Fang, Wei Su, Xinyu Wang +2
Long-lived particle (LLP) is one of the well-motivated targets for current collider experiments searching for the physics beyond the Standard Model. In recent years, many dedicated…
New Physics Search at the CEPC: a General Perspective
Xiaocong Ai, Stefan Antusch, Peter Athron +211
The Circular Electron-Positron Collider (CEPC), a proposed next-generation Higgs factory, provides new opportunities to explore physics beyond the Standard Model (SM). With its cle…
Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Dark Matter and Electroweak Phase Transition in the Symmetric Georgi-Machacek Model
Chih-Ting Lu, Yongcheng Wu, Siyu Xu
We present a comprehensive investigation of the symmetric Georgi-Machacek (GM) model, focusing on the dark matter (DM) in the model and the electroweak phase transition (EWPT…
Probing long-lived doubly charged scalar in the Georgi-Machacek model at the LHC and in far detectors
Chih-Ting Lu, Xinyu Wang, Xinqi Wei +1
Searching for long-lived particles (LLPs) beyond the Standard Model (SM) is a promising direction in collider experiments. The Georgi-Machacek (GM) model extends the scalar sector…
