Event Details

Dark matter constitutes more than 80% of matter in the universe, but it’s true nature remains unknown except its gravitational effects. Despite extensive experimental studies over several decades aimed at detecting weakly interacting massive particle (WIMP) dark matter candidates, no positive signals have been found.This lack of success has led physicists to explore alternative scenarios, including light dark matter (LDM) and axion-like particles (ALPs). In this scenario, LDM is produced through the conversion of standard model photons via kinetic mixing, while ALPs are produced through Primakoff process, which also converts standard model photons into ALPs. Therefore, the more photons produced, the more dark matter can be produced. In this regard, accelerator-driven fixed target experiment provide an ideal experimental condition for searching for dark sector particles. In this presentation, I will discuss my research activities aimed at searching for dark sector particles using various setups of accelerator-driven experiments including DUNE, ICARUS and so on.
