Long-lived particles are predicted by many Beyond the Standard Model (BSM) theories, such as the Supersymmetry and Hidden Valley Models, and can serve as a viable candidate for the Dark Matters (DM). We have searched for Long-Lived Particles (LLPs) that decays in the muon chambers in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider with Run 3 Data. The search targets...

In this study, we explored the Vector Scotogenic Model in the context of addressing the Dark Matter problem. Guided by unitarity considerations, our focus was directed toward the scenario involving fermionic dark matter. We found that co-annihilations play a crucial role in achieving the observed dark matter relic abundance. Furthermore, the effects of co-annihilation divide the parameter...

DAMIC-M (Dark Matter in CCDs at Modane) is a leading experiment that searches for sub-GeV Dark Matter (DM) using Skipper CCDs under the French Alps at the Laboratoire Souterrain de Modane (LSM). The capability of single-electron detection, combined with an extremely low dark current, results in an energy threshold of a few eV. A first prototype phase, the Low Background Chamber (LBC), has been...

The Higgs boson plays a fundamental role in the Standard Model (SM) of particles, one of them, is to unitarize the elastic scattering of the gauge bosons at tree level. Additionally, this analysis impose an upper bound on the Higgs Mass. Despite the extraordinary experimental success, which culminate in the discovery of the Higgs boson in 2012, the SM cannot explain the astrophysical and...
