Improving the Angular Resolution of IBD Events Using Neutron Capture Information in Super-Kamiokande
Qishan Liu, Kenny C. Y. Ng
One of the most important neutrino interactions is the Inverse Beta Decay (IBD). However, the IBD events typically carry no directional information in water Cherenkov detectors as…
New Physics Opportunities at Neutrino Facilities: BSM Physics at Accelerator, Atmospheric, and Reactor Neutrino Experiments
Koun Choi, Doojin Kim, Jong-Chul Park +22
Since the discovery of the Higgs boson, the long-standing task at hand in particle physics is the search for new physics beyond the Standard Model, which accounts for only about 5\…
Searching for Particle Dark Matter with eROSITA Early Data
Chingam Fong, Kenny C. Y. Ng, Qishan Liu
Many well motivated dark matter (DM) particle candidates can decay into detectable X-ray photons. We analyze the Final Equatorial Depth Survey (eFEDS) data from eROSITA early data…
Improving HAWC dark matter constraints with Inverse-Compton Emission
Dylan M. H. Leung, Kenny C. Y. Ng
The particle nature of dark matter (DM) has been a long-lasting mystery. Many models suggest that DM could decay or self annihilate into standard model particles, and thus could be…
Sensitivity floor for primordial black holes with neutrino searches
Qishan Liu, Kenny C. Y. Ng
Primordial black holes~(PBHs) formed in the early Universe are well-motivated dark matter~(DM) candidates over a wide range of masses. These PBHs could emit detectable signals in t…
