Search for new light vector boson using at BESIII and Belle II
Kayoung Ban, Yongsoo Jho, Youngjoon Kwon +3
We investigate various search strategies for light vector boson in mass range using associated channels at BESIII and Belle II: (i) $J/Ψ\to η_…
Stellar cooling, inelastic dark matter, and XENON
Wai-Yee Keung, Danny Marfatia, Po-Yan Tseng
We consider a novel scenario of dark photon-mediated inelastic dark matter to explain the white dwarf cooling excess suggested by its luminosity function, and the excess in electro…
Leptonic New Force and Cosmic-ray Boosted Dark Matter for the XENON1T Excess
Yongsoo Jho, Jong-Chul Park, Seong Chan Park +1
The recently reported excess in XENON1T is explained by new leptonic forces, which are free from gauge anomalies. We focus on two scenarios with and without dark matter. In Scenari…
Gravitational wave signals of dark matter freeze-out
Danny Marfatia, Po-Yan Tseng
We study the stochastic background of gravitational waves which accompany the sudden freeze-out of dark matter triggered by a cosmological first order phase transition that endows…
Heating neutron stars with GeV dark matter
Wai-Yee Keung, Danny Marfatia, Po-Yan Tseng
An old neutron star (NS) may capture halo dark matter (DM) and get heated up by the deposited kinetic energy, thus behaving like a thermal DM detector with sensitivity to a wide ra…
Light gauge boson interpretation for and the anomaly at the J-PARC KOTO experiment
Yongsoo Jho, Sung Mook Lee, Seong Chan Park +2
We discuss a list of possible light gauge boson interpretations for the long-standing experimental anomaly in and also recent anomalous excess in $K_L \rightarrow π^0 + \…
