Higgs Inflation at the Pole
Simon Cléry, Hyun Min Lee, Adriana G. Menkara
We propose a novel possibility for Higgs inflation where the perturbative unitarity below the Planck scale is ensured by construction and the successful predictions for inflation a…
Graceful exit from inflation and reheating with twin waterfalls
Hyun Min Lee, Adriana Menkara
We study the hybrid inflation with a pseudo-Nambu-Goldstone boson inflaton and two waterfall scalar fields. The symmetry for the waterfall fields keeps inflaton potential fla…
Self-resonant Dark Matter
Hyun Min Lee
We present a review on the self-resonant dark matter scenarios where multiple components of dark matter give rise to a resonant condition in the -channel diagrams for their comp…
On the Weyl gravity extension of Higgs inflation
Shuntaro Aoki, Hyun Min Lee
We consider the embedding of Higgs inflation with a non-minimal coupling into the Weyl gravity. In this model, the effective current-current interactions from the heavy Weyl gauge…
Pseudo-Nambu-Goldstone inflation with twin waterfalls
Hyun Min Lee, Adriana Menkara
We propose a pseudo-Nambu-Goldstone inflation where twin waterfall fields coupled to the inflaton are responsible for the graceful exit from inflation by a waterfall transition. In…
A Model of Vector-like Leptons for the Muon and the Boson Mass
Hyun Min Lee, Kimiko Yamashita
We consider a simple extension of the Standard Model (SM) with a vector-like lepton and a local symmetry, motivated by the recent experimental anomalies in the muon a…
Models for Self-resonant Dark Matter
Seong-Sik Kim, Hyun Min Lee, Bin Zhu
We consider a new mechanism for enhancing the self-scattering and annihilation cross sections for dark matter with multiple components but without a light mediator. The lighter dar…
Reheating and Dark Matter Freeze-in in the Higgs- Inflation Model
Shuntaro Aoki, Hyun Min Lee, Adriana G. Menkara +1
We study the post-inflationary dynamics for reheating and freeze-in dark matter in the Higgs- inflation model. Taking the perturbative approach for reheating, we determine the…
Towards a Model of Quarks and Leptons
Y. H. Ahn, Sin Kyu Kang, Hyun Min Lee
We propose an extra-dimension framework on the orbifold for understanding the origin of the fermion mass and mixing hierarchies. Introducing the flavor symmetry {\…
Seesaw lepton masses and muon from heavy vector-like leptons
Hyun Min Lee, Jiseon Song, Kimiko Yamashita
We propose a model for the vector-like lepton to explain the small muon mass by a seesaw mechanism, based on lepton-specific two Higgs doublet models with a local symmetry.…
Self-resonant Dark Matter
Seong-Sik Kim, Hyun Min Lee, Bin Zhu
We present a novel mechanism for Sommerfeld enhancement for dark matter interactions without the need for light mediators. Considering a model for two-component dark matter with a…
Cosmology of Linear Higgs-Sigma Models with Conformal Invariance
Hyun Min Lee, Adriana G. Menkara
We consider general linear Higgs-sigma models as ultra-violet completions of the Higgs inflation. We introduce general higher curvature terms beyond Einstein gravity and recast the…
Leptoquark Option for -meson Anomalies and Leptonic Signatures
Hyun Min Lee
We entertain the option of scalar leptoquarks to explain the anomalies in the semi-leptonic decays of -mesons and the discrepancies in the lepton 's including the recen…
Flux-mediated Dark Matter
Yoo-Jin Kang, Hyun Min Lee, Adriana G. Menkara +1
We propose a new mechanism to communicate between fermion dark matter and the Standard Model (SM) only through the four-form flux. The four-form couplings are responsible for the r…
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…
Dark mesons as self-interacting dark matter
Hyun Min Lee
We review the current status of model building for light dark matter in theories of QCD-like gauge groups in the hidden sector. The focus is upon the dark mesons with the …

Ligong Bian, Hyun Min Lee, Chan Beom Park
We investigate the role of a local symmetry for the problem of CP violation in the effective theory for two Higgs doublet models and its microscopic counterparts. First, in…
The Clockwork Standard Model
Yoo-Jin Kang, Soonbin Kim, Hyun Min Lee
We consider various bulk fields with general dilaton couplings in the linear dilaton background in five dimensions as the continuum limit of clockwork models. We show that the loca…
Exothermic Dark Matter for XENON1T Excess
Hyun Min Lee
Motivated by the recent excess in the electron recoil from XENON1T experiment, we consider the possibility of exothermic dark matter, which is composed of two states with mass spli…
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…
Effective theory for self-interacting dark matter and massive spin-2 mediators
Yoo-Jin Kang, Hyun Min Lee
We consider the effective theory for self-interacting dark matter with arbitrary spin and go beyond the previous discussion in the literature by introducing a massive spin-2 partic…
Dark matter self-interactions from spin-2 mediators
Yoo-Jin Kang, Hyun Min Lee
We propose a new mechanism for rendering dark matter self-interacting in the presence of a massive spin-2 mediator. The derived Yukawa-type potential for dark matter is independent…
Beyond the Starobinsky model for inflation
Dhong Yeon Cheong, Hyun Min Lee, Seong Chan Park
We single out the Starobinsky model and its extensions among generic gravity as attractors at large field values for chaotic inflation. Treating a curvature term as a…
Lightening Gravity-Mediated Dark Matter
Yoo-Jin Kang, Hyun Min Lee
We revisit the scenario of a massive spin-2 particle as the mediator for communicating between dark matter of arbitrary spin and the Standard Model. Taking the general couplings of…
