A Unified Dark Matter Explanation for and the Super-Kamiokande Antineutrino Excess
Shu-Yu Ho, Jongkuk Kim, Pyungwon Ko
Recent results from Super-Kamiokande and Belle II have revealed intriguing excesses over Standard Model expectations. Super-Kamiokande observes a mild excess of -like…
Excess and DM semi-annihilation
Jongkuk Kim, Pyungwon Ko
In 2023, Belle II collaboration announced the observarion of the decay channel for the first time. This decay channel provides a clean signal with high preci…
Linking the KM3-230213A Neutrino Event to Dark Matter Decay and Gravitational Wave signals
Sarif Khan, Jongkuk Kim, Pyungwon Ko
The KM3NeT collaboration recently reported the detection of an ultra-high-energy (UHE) neutrino event, dubbed KM3-230213A. This is the first observed neutrino event with energy of…
Multi-component dark matter and Galactic 511 keV -ray emission
Sarif Khan, Jinsu Kim, Jongkuk Kim +1
We study multi-component dark matter scenarios and the Galactic 511 keV -ray emission line signal in the framework of a local, dark extension of the Standard Model. A…
Recent excess and muon illuminating light dark sector with Higgs portal
Shu-Yu Ho, Jongkuk Kim, Pyungwon Ko
The Belle II collaboration recently announced that they observed the decay process for the first time. This dineutrino mode of has b…
