For the past two decades, dual-phase xenon time projection chambers (TPCs) have dominated the search for Weakly Interacting Massive Particles (WIMPs). Their scalability and advanced technology also grant them world-leading sensitivity to other Beyond Standard Model (BSM) physics and rare or exotic neutrino phenomena. The LUX-ZEPLIN (LZ) experiment, utilizing a 7-tonne liquid xenon target, is...

The Any Light Particle Search II (ALPS II) is a 'light-shining-through-a-wall' experiment currently running at DESY in Hamburg, Germany, searching for axions and axion-like particles. 'light-shining-through-a-wall' experiments use a strong laser to shine light through a strong magnetic field to convert a fraction of the light into axions. The unconverted light is blocked by a wall while the...

WISPFI (WISP Searches on a Fiber Interferometer) is a novel table-top experiment designed to detect photon-axion conversion using resonant mixing. The experiment employs hollow-core photonic crystal fibers (HC-PCF) to fulfill the resonant condition, which can be precisely tuned by adjusting the gas pressure within the fiber. This technique enables the probing of an unexplored axion mass range...

A range of haloscope searches are currently probing axions in the mass range ~2-40 μeV. However, simulations of the axion field in the early Universe are increasingly pointing towards heavier masses if we want the axion to comprise all of the Dark Matter in the Universe. I will briefly review these developments and then I will present The Canfranc Axion Detection Experiment (CADEx), a proposed...

The SERAPH (SupERconducting Axion and Paraphoton Haloscope) experiment is a family of superconducting haloscopes being developed by the Superconducting Quantum Materials and Systems (SQMS) Center to search for wavelike dark matter. This presentation will focus on preliminary results from our dark photon dark matter search using a widely-tunable SRF cavity operating between 4-7 GHz, nicknamed...

The small-scale distribution of dark matter is expected to

feature fine-grained substructure on solar-system scales, arising from
the gravitational folding of an initially smooth phase-space sheet into
many overlapping streams. For axions—especially in the post-inflationary
scenario—early-Universe clustering can further amplify these densities.
While such substructure is typically... -

A collaboration between three main laboratories of CNRS, Université Grenoble-Alpes and DMAG/IBS in South Korea (ex-CAPP) is bringing together key expertises to build and operate several haloscopes for axion dark matter searches with unprecedented sensitivity. Based on existing infrastructures at Grenoble like the 9 T/43 T modular hybrid magnet of LNCMI recently put in operation up to 8.5 T/42...

The DMRadio program is developing a suite of experiments to probe QCD axions in the sub-1 μeV mass range, a theoretically motivated regime with implications for grand unified theories and pre-inflationary cosmology. The first of these, DMRadio-50L, is undergoing commissioning and targets axion masses from 5 kHz to 5 MHz. Accessing this low-mass QCD axion regime poses unique experimental...
