Mono-Higgs signature in a singlet fermionic dark matter model
Yeong Gyun Kim, Kang Young Lee, Soo-hyeon Nam
We investigate mono-Higgs production as a probe of singlet fermionic dark matter (SFDM) at the LHC. In this framework, a Standard Model (SM) gauge-singlet Dirac fermion serves as t…

Planck isocurvature constraint on primordial black holes lighter than a kiloton
TaeHun Kim, Jinn-Ouk Gong, Donghui Jeong +3
We demonstrate that primordial black holes (PBHs) lighter than , which evaporated before the big bang nucleosynthesis, can induce significant isocurvature perturb…

Probing the 3+1 neutrino model in the SHiP experiment
Ki-Young Choi, Yu Seon Jeong, Sung Hyun Kim +7
In this study, as an extension of our previous work, we estimate the sensitivity of the Search for Hidden Particles (SHiP) experiment to the 3+1 model using the charged-current dee…
