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…
Searching for Dark Photon Tridents Through Primordial Black Hole Signatures
Kingman Cheung, C. J. Ouseph, Po-Yan Tseng +1
The detection of gamma-ray signals from primordial black holes (PBHs) could provide compelling evidence for their role as a dark matter candidate, particularly through the observat…
Unveiling the Invisible: ALPs and Sterile Neutrinos at the LHC and HL-LHC
Kingman Cheung, C. J. Ouseph, Sin Kyu Kang
We investigate the potential of using the signature of mono-Higgs plus large missing energies to constrain on two new physics models, namely the model of an axion-like particle (AL…
Exploring interference effects between two ALP effective operators at the LHC
Kingman Cheung, Chih-Ting Lu, C. J. Ouseph +1
We observe that most studies of axion-like particle (ALP) production channels at the Large Hadron Collider (LHC) focus on a single type of ALP operator for each process in the effe…
Probing the Gauge-boson Couplings of Axion-like Particle at the LHC and High-Luminosity LHC
Kingman Cheung, Wanyon Hsiao, C. J. Ouseph +1
In this work, we calculate the sensitivities on the gauge-boson couplings , , and of an axion-like particle (ALP) that one can achieve at the LHC with $…
Interpretation of excess in using a light axion-like particle
Kingman Cheung, C. J. Ouseph
We interpret the recent excess in a rare decay of the Higgs boson, , using a light axion-like particle (ALP) in the massrange GeV.The dominant decay of such a…
Probing dark photons from a light scalar at Belle II
Kingman Cheung, Yongkyu Kim, Youngjoon Kwon +3
In the minimal extension of the Standard Model (SM), a new gauge boson referred to as "dark photon" is predicted. The dark-photon mass can be generated from an additional Hi…
NANOGrav Signal and PBH from the Modified Higgs Inflation
Kingman Cheung, C. J. Ouseph, Po-Yan Tseng
This study investigates the classical Higgs inflation model with a modified Higgs potential featuring a dip. We examine the implications of this modification on the generation of c…

In this study, we calculate the sensitivity reach on the vector leptoquark (LQ) at the experiments proposed in Forward Physics Facility (FPF), including FASER, FASER…
Sensitivities on dark photon from the Forward Physics Experiments
Kingman Cheung, C. J. Ouseph
Neutrino-electron scattering experiments can explore the potential presence of a light gauge boson which arises from an additional group, or a dark photon wh…
Constraining the Active-to-Heavy-Neutrino transitional magnetic moments associated with the interactions at FASER
Kingman Cheung, C. J. Ouseph
We investigate the effects of the transitional magnetic dipole moment of the active-to-heavy-neutrino associated with a new neutral gauge boson on neutrino-nucleon scattering…
