A Unified Dark Matter Explanation for $B^{+} \to K^{+} I^½ I^ˉ ½$ 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 $I^ˉ ½_{e}$ -like…

Multi-component dark matter and Galactic 511 keV $I^^{3}$ -ray emission

Sarif Khan, Jinsu Kim, Jongkuk Kim +1

We study multi-component dark matter scenarios and the Galactic 511 keV $I^^{3}$ -ray emission line signal in the framework of a local, dark $U (1)_{D}$ extension of the Standard Model. A…

Recent $B^{+} \to K^{+} I^½ I^ˉ ½$ excess and muon $g - 2$ illuminating light dark sector with Higgs portal

Shu-Yu Ho, Jongkuk Kim, Pyungwon Ko

The Belle II collaboration recently announced that they observed the $B^{+} \to K^{+} I^½ I^ˉ ½$ decay process for the first time. This dineutrino mode of $B^{+} \to K^{+} I^½ I^ˉ ½$ has b…
