From LUX-ZEPLIN to Colliders: Probing Higgsino Dark Matter
Kingman Cheung, Sin Kyu Kang, Ranjeet Kumar
The high-energy nuclear recoil event with recoil energy observed by the LZ collaboration provides an exciting hint toward a model with a $1.1\text{ TeV…
Neutrino Dipole Portal
Sin Kyu Kang, C. J. Ouseph
The neutrino dipole portal (NDP) is a minimal and predictive extension of the Standard Model, in which a transition magnetic moment operator couples an active neutrino to a heavy n…
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…
