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…
Scalar dark matter multiplet of global symmetry
U-Rae Kim, Jungil Lee, Soo-hyeon Nam
We study two types of models involving a scalar dark matter multiplet of global symmetry. These models are distinguished by the absence (Type I) or presence (Type II) of a s…
Novel Search for Light Dark Photon in the Forward Experiments at the LHC
Yeong Gyun Kim, Kang Young Lee, Soo-hyeon Nam
We propose a novel approach for discovering a light dark photon in the forward experiments at the LHC, including the SND@LHC and the FASER experiments. Assuming the dark photon is…
Evolution of the spin of late-type galaxies caused by galaxy-galaxy interactions
Jeong-Sun Hwang, Changbom Park, Soo-hyeon Nam +1
We use N-body/hydrodynamic simulations to study the evolution of the spin of a Milky Way-like galaxy through interactions. We perform a controlled experiment of co-planner galaxy-g…
