A Two-Component Dark Matter Model and its Associated Gravitational Waves
Francesco Costa, Sarif Khan, Jinsu Kim
We consider an extension of the Standard Model that accounts for the muon tension and neutrino masses and study in detail dark matter phenomenology. The model under considera…
CMB from a Gauss-Bonnet-induced de Sitter fixed point
Shinsuke Kawai, Jinsu Kim
In the gravitational effective theories including higher curvature terms, cosmological solutions can have nontrivial de Sitter fixed points. We study phenomenological implications…
A multi-component SIMP model with
Soo-Min Choi, Jinsu Kim, Pyungwon Ko +1
Multi-component dark matter scenarios are studied in the model with dark gauge symmetry that is broken into its product subgroup á la Krauss-Wilczek mecha…
Connecting between inflation and dark matter in models with gauged symmetry
Soo-Min Choi, Jinsu Kim, Hyun Min Lee +1
We investigate the possibility of unifying the inflation and dark matter physics in the minimal model for a complex scalar dark matter with gauged symmetry. The dark local $U…
Searching for Flavored Gauge Bosons
Eung Jin Chun, Arindam Das, Jinsu Kim +1
Standard Model may allow an extended gauge sector with anomaly-free flavored gauge symmetries, such as , , and , where are fla…
Effective Approximation of Electromagnetism for Axion Haloscope Searches
Younggeun Kim, Dongok Kim, Junu Jung +3
We applied an effective approximation into Maxwell's equations with an axion interaction for haloscope searches. A set of Maxwell's equations acquired from this approximation descr…
Freeze-In Dark Matter from a sub-Higgs Mass Clockwork Sector via the Higgs Portal
Jinsu Kim, John McDonald
The clockwork mechanism allows extremely weak interactions and small mass scales to be understood in terms of the structure of a theory. A natural application of the clockwork mech…
Clockwork Higgs portal model for freeze-in dark matter
Jinsu Kim, John McDonald
The clockwork mechanism can explain interactions which are dimensionally very weak without the need for very large mass scales. We present a model in which the clockwork mechanism…
Leptonic Precision Test of Leptophilic Two-Higgs-Doublet Model
Eung Jin Chun, Jinsu Kim
The type X (lepton-specific) two-Higgs-doublet model at large becomes leptophilic and thus allows a light pseudoscalar accommodating the observed muon deviation w…
Multifield dynamics of supersymmetric Higgs inflation in SU(5) GUT
Shinsuke Kawai, Jinsu Kim
We study the Higgs inflation model realized in the supersymmetric SU(5) grand unified theory (GUT), focusing on its multifield dynamics and prediction of cosmological observables.…
Testing supersymmetric Higgs inflation with non-Gaussianity
Shinsuke Kawai, Jinsu Kim
We investigate multi-field signatures of the nonminimally coupled supersymmetric Higgs inflation-type cosmological scenario, focusing on the two-field Higgs-lepton inflation model…
Higgs-portal assisted Higgs inflation with a sizeable tensor-to-scalar ratio
Jinsu Kim, Pyungwon Ko, Wan-Il Park
We show that the Higgs portal interactions involving extra dark Higgs field can save generically the original Higgs inflation of the standard model (SM) from the problem of a deep…
Two-field inflation with non-minimal coupling
Jinsu Kim, Yoonbai Kim, Seong Chan Park
Motivated by the recent `Higgs-inflation' scenario based on a single inflaton field, we consider more generic two-field inflation with non-minimal coupling term. The generic analyt…
