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-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…
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…
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_…
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…
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…
