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…
Exothermic dark mesons in light of electron recoil excess at XENON1T
Soo-Min Choi, Hyun Min Lee, Bin Zhu
We consider a novel mechanism to realize exothermic dark matter with dark mesons in the limit of approximate flavor symmetry in a dark QCD. We introduce a local dark symmet…
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…
Vector SIMP dark matter with approximate custodial symmetry
Soo-Min Choi, Hyun Min Lee, Yann Mambrini +1
We consider a novel scenario for Vector Strongly Interacting Massive Particle (VSIMP) dark matter with local symmetry in the dark sector. Similarly to the…
Unitary inflaton as decaying dark matter
Soo-Min Choi, Yoo-Jin Kang, Hyun Min Lee +1
We consider the inflation model of a singlet scalar field (sigma field) with both quadratic and linear non-minimal couplings where unitarity is ensured up to the Planck scale. We a…
Unitarizing SIMP scenario with dark vector resonances
Soo-Min Choi, Hyun Min Lee, Pyungwon Ko +1
Dark pion is the one of the most natural and realistic model to make contact interactions among models of the Strongly Interacting Massive Particle (SIMP). In thi…
Lepto-Quark Portal Dark Matter
Soo-Min Choi, Yoo-Jin Kang, Hyun Min Lee +1
We consider the extension of the Standard Model with scalar leptoquarks as a portal to dark matter (DM), motivated by the recent anomalies in semi-leptonic -meson decays. Taking…
Proceedings of the first MadAnalysis 5 workshop on LHC recasting in Korea
Benjamin Fuks, Samuel Bein, Guillaume Chalons +22
We present the activities performed during the first MadAnalysis 5 workshop on LHC recasting that has been organized at High 1 (Gangwon privince, Korea) on August 20-27, 2017. This…
Resolving phenomenological problems with strongly-interacting-massive-particle models with dark vector resonances
Soo-Min Choi, Hyun Min Lee, Pyungwon Ko +1
We consider a light dark matter candidate which is produced by the freeze-out mechanism with annihilations, the so called Strongly Interacting Massive Particles (SI…
Forbidden Channels and SIMP Dark Matter
Soo-Min Choi, Yoo-Jin Kang, Hyun Min Lee
In this review, we focus on dark matter production from thermal freeze-out with forbidden channels and SIMP processes. We show that forbidden channels can be dominant to produce da…
SIMP dark matter and its cosmic abundances
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
We give a review on the thermal average of the annihilation cross-sections for and general higher-order processes. Thermal average of higher order annihilations hi…
A minimal flavored for -meson anomalies
Ligong Bian, Soo-Min Choi, Yoo-Jin Kang +1
We consider an anomaly-free model with favorable couplings to heavy flavors in the Standard Model(SM), as motivated by -meson anomalies at LHCb. Taking the charg…
Vector SIMP dark matter
Soo-Min Choi, Yonit Hochberg, Eric Kuflik +4
Strongly Interacting Massive Particles (SIMPs) have recently been proposed as light thermal dark matter relics. Here we consider an explicit realization of the SIMP mechanism in th…
Cosmic abundances of SIMP dark matter
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
Thermal production of light dark matter with sub-GeV scale mass can be attributed to self-annihilation processes. We consider the thermal average for annihilation…

Soo-Min Choi, Yoo-Jin Kang, Hyun Min Lee
We consider thermal production mechanisms of self-interacting dark matter in models with gauged symmetry. A complex scalar dark matter is stabilized by the , that is the…
Diphoton resonance confronts dark matter
Soo-Min Choi, Yoo-Jin Kang, Hyun Min Lee
As an interpretation of the 750 GeV diphoton excesses recently reported by both ATLAS and CMS collaborations, we consider a simple extension of the Standard Model with a Dirac ferm…

Soo-Min Choi, Hyun Min Lee
We consider a resonant SIMP dark matter in models with two singlet complex scalar fields charged under a local dark . After the is broken down to a discrete…
Inflection point inflation and reheating
Soo-Min Choi, Hyun Min Lee
We revisit the inflection point inflation with an extended discussion to large field values and consider the reheating effects on the inflationary predictions. Parametrizing the re…
