SPACE seminar: Raoul Serao - "New method to detect dark matter and X17 as a new portal as dark matter"

Tuesday 3 Feb 2026, 12:00 → 13:00 Europe/Rome

Aula 4 (San Marcellino)

Speaker: Raoul Serao (Dipartimento di Fisica "E.R. Caianiello", Università di Salerno)

Abstract: We present a new approach to dark matter detection based on single-arm interferometry and investigate the X17 boson as a possible portal between the dark sector and the Standard Model. Ultralight scalar field dark matter can induce tiny, coherent effects on photon propagation, leading to measurable phase shifts in precision interferometric setups. We discuss how the presence of the X17 mediator may enhance the interaction between dark matter and ordinary matter, providing observable signatures in current and near-future experiments. This framework offers a complementary and testable strategy for probing dark matter beyond conventional detection methods.
