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 a…

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…
