Search for doubly charged scalars in type-II seesaw mechanism through photon fusion at the LHC
Hang Zhou, Ning Liu
Small neutrino masses can be generated through the well-known seesaw mechanisms, among which the type-II scenario predicts a triplet scalar with doubly charged components. Except f…

Probing Gauged Sub-GeV Dark Matter via Cosmic Ray Cooling in Active Galactic Nuclei
Arvind Kumar Mishra, Ning Liu, Chih-Ting Lu
Cosmic rays (CRs) traversing the dark matter (DM) spike surrounding active galactic nuclei (AGNs) can be cooled through interactions with DM particles. In this study, we investigat…

Neutron Star Collapse From Accretion: a Probe of Massive Dark Matter Particles
Ning Liu, Arvind Kumar Mishra
We explore the multi-scatter capturing of the massive dark matter (DM) particle inside the neutron star via a momentum-dependent dark matter-nucleon scattering cross-section. We fi…
