Munich Dark Matter Meeting - Jan Jerhot - Dark sector searches at fixed-target experiments

Tuesday Jun 16, 2026, 12:30 PM → 1:30 PM Europe/Berlin

A.2.25 - Atlas West (MPP)

Dark sector portals provide a possible connection between the Standard Model and dark matter through mediator fields that can manifest as light, feebly interacting particles (FIPs). Although primarily sensitive to masses in the MeV–GeV range, fixed-target experiments are among the most promising approaches for searching for FIPs, combining high-intensity beams with low-background environments. As a result, they can probe FIP–SM couplings more than four orders of magnitude smaller than those typically accessible at collider experiments.

In this talk, I will present an overview of the most common dark-sector portals and past and current fixed-target experiments, as well as future prospects, with a particular emphasis on proton fixed-target facilities. To compare the sensitivities of different experiments under common theoretical assumptions, it is useful to employ tools that enable the interpretation of a wide class of models and the straightforward implementation of new experimental geometries, including the incorporation of real experimental data. One such tool is the ALPINIST framework, a publicly available code co-developed at MPP in Munich.
