2024年11月18日 · Direct detection of light dark matter can be significantly enhanced by up-scattering of dark matter with energetic particles in the cosmic ambient. This boosted dark matter flux can reach kinetic energies up to tens of MeV, while the typical kinetic energies of GeV mass dark matter particles in the Milky Way halo are of the order of keV.

2025年1月20日 · The trouble in detecting low mass dark matter due to its low kinetic energy can be ameliorated in the boosted dark matter framework, where a sub-population of galactic dark …

Advancements in Nb _3 3Sn 12 T Cos-Theta Dipole Development for Next-Generation Accelerators: The INFN-CERN Collaboration on the FalconD Project

2023年5月16日 · We extend the Standard Model (SM) particle content with a SM singlet DM particle χ and an axion-like particle (ALP) a. The interactions between ALP, SM particles, and DM are generated by higher dimensional effective operators. This setup allows the production of DM χ from SM bath through the mediation of ALP, via ALP-portal processes.
