Pseudo-scalar dark matter from a broken gauged symmetry
Junho Kang, Sarif Khan, Jongkuk Kim +1
We propose a novel model for pseudo-scalar dark matter (PSDM) by extending the Standard Model (SM) with a dark gauged symmetry, but without dark charged fermions. We impos…
Higgs Scattering and Entanglement in SMEFT
Hyun Min Lee, Rojalin Padhan
We regard the weak isospin of the Higgs doublet as a qubit and classify the entanglement measures for the Higgs scattering in the Standard Model Effective Field Theories (SMEFT) an…
Pseudo-Nambu-Goldstone inflation with symmetric waterfall fields
Hyun Min Lee, Adriana G. Menkara
We propose a hybrid inflation model where a pseudo-Nambu-Goldstone boson inflaton couples to waterfall scalar fields respecting a symmetry. We identify the phases for the…
Decaying vector dark matter with low reheating temperature for KM3NeT signal and its impact on gravitational waves
Sarif Khan, Jongkuk Kim, Hyun Min Lee
We propose a new model to explain the KM3NeT neutrino event through a low reheating scenario with a suppression in the GW spectrum originating from cosmic string networks. To achie…
Self-resonant dark matter with gauged symmetry
Lucca Radicce Justino, Seong-Sik Kim, Hyun Min Lee +1
We present a new model for two-component scalar dark matter (DM), consisting of two complex scalar fields. In this model, both the DM components are stable due to the remaining $Z_…
Neutrino masses and mixed dark matter from doublet and singlet scalars
Jongkuk Kim, Seong-Sik Kim, Hyun Min Lee +1
We consider the extension of the Standard Model with an inert scalar doublet, three right-handed neutrinos, and singlet scalar fields, and . In this model, neutrino masses a…
WIMP-FIMP option and neutrino masses via a novel anomaly-free B-L symmetry
Sarif Khan, Hyun Min Lee
We propose a novel model with singlet dark matter fermions composed of WIMP and FIMP, which is anomaly-free without a need for introducing right-handed neutrinos. Ferm…
Higgs portal vector dark matter at a low reheating temperature
Sarif Khan, Jongkuk Kim, Hyun Min Lee
In this study, we explore vector dark matter (DM) production in the early Universe focusing on a scenario with a low reheating temperature. One can achieve low reheat temperature i…
Standard Model anomalies and vacuum stability for lepton portals with extra symmetry
Carlo Branchina, Hyun Min Lee, Kimiko Yamashita
Recently, the experimental values of the muon and of the boson mass have both indicated significant deviations from the SM predictions, motivating the explor…
Small Neutrino Masses from a Decoupled Singlet Scalar Field
Jongkuk Kim, Seong-Sik Kim, Hyun Min Lee +1
We propose a unified solution with discrete symmetry for small neutrino masses and stability of dark matter. The Standard Model is extended with an inert doublet scalar, a da…
Muon and Proton Lifetime in SUSY SU(5) GUTs with Split Superpartners
Seong-Sik Kim, Hyun Min Lee, Sung-Bo Sim
We consider the interplay of the muon anomaly and the proton decay in the SUSY SU(5) GUTs with generation-independent scalar soft masses. In these scenarios, we introduce a n…
The lepton portals for muon , boson mass and dark matter
Seong-Sik Kim, Hyun Min Lee, Adriana G. Menkara +1
We propose a novel model which extends the Standard Model (SM) by introducing a gauge symmetry. In this model, a dark Higgs doublet and a Higgs bi-doublet can c…
The lepton portals for muon , boson mass and dark matter
Seong-Sik Kim, Hyun Min Lee, Adriana G. Menkara +1
We propose a novel model for lepton flavor and dark matter based on the gauge symmetry and vector-like leptons in its fundamental representations. We introduce a dark $SU…
