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…
Phenomenology of a two-component dark matter model
Yeong Gyun Kim, Kang Young Lee, Soo-hyeon Nam
We study a two-component dark matter model consisting of a Dirac fermion and a complex scalar charged under new U(1) gauge group in the hidden sector. The dark fermion plays the do…
Vacuum stability of conformally invariant scalar dark matter models
Yeong Gyun Kim, Kang Young Lee, Jungil Lee +1
We discuss vacuum structure and vacuum stability in classically scale-invariant renormalizable models with a scalar dark matter multiplet of global O(N) symmetry together with an e…
Singlet Fermionic Dark Matter with Dark
Dong-Won Jung, Soo-hyeon Nam, Chaehyun Yu +2
We present a fermionic dark matter model mediated by the hidden gauge boson. We assume the QED-like hidden sector which consists of a Dirac fermion and U(1) gauge symmetry, and…
Conformal invariance and singlet fermionic dark matter
Yeong Gyun Kim, Kang Young Lee, Soo-hyeon Nam
We study a classically scale-invariant model with an electroweak singlet complex scalar mediator together with an anomaly free set of two fermionic dark matters. We introduce $U(1)…
Collider probes of singlet fermionic dark matter scenarios for the Fermi gamma-ray excess
Yeong Gyun Kim, Chan Beom Park, Seodong Shin
We investigate the collider signatures of the three benchmark points in the singlet fermionic dark matter model. The benchmark points, which were introduced previously to explain t…
