Over the next several years, fixed target and collider experiments will greatly improve our coverage of dark matter below the GeV scale. In this talk I will present a theoretical overview of these models and outline various search strategies at existing and future accelerator experiments.
The Belle II experiment at the asymmetric $e^+e^-$ collider, SuperKEKB, is a substantial upgrade of the Belle/KEKB experiment. Belle II aims to record 50 ab$^{-1}$ of data over the course of the project. During the first physics runs in 2018-2020, around 100 fb$^{-1}$ of data were collected. These early data include specifically-designed low-multiplicity triggers which allow a variety of...
Results on the sensitivity of ILC and CLIC to WIMP dark matter (DM) pair production are reviewed for processes with mono-photon signature, when DM production is accompanied by a hard photon emission from the initial state radiation. In the effective field theory (EFT) approach scales of up to 3 TeV can be tested at ILC for different operator types and DM masses almost up to half the collision...
The International Axion Observatory (IAXO) is a large-scale axion helioscope that will search for axions and axion-like particles produced in the Sun. It is conceived to reach a sensitivity on the axion-photon coupling in the range of 10-12 GeV-1. To facilitate the way to the gigantic IAXO helioscope, a smaller experiment BabyIAXO is in the construction phase. BabyIAXO...
Detection mechanisms for low mass bosonic dark matter candidates, such the axion or hidden photon, leverage potential interactions with electromagnetic fields, whereby the dark matter (of unknown mass) on rare occasion converts into a single photon. We report the development of a novel microwave photon counting technique and a new exclusion limit on hidden photon dark matter. We operate a...
