Dark Matter Radio 50L (DMRadio-50L) is an experiment designed to search for pre-inflationary axion dark matter in the mass range between 20 peV/$c^2$ and 20 neV/$c^2$, corresponding to Compton frequencies between 5 kHz and 5 MHz. This talk presents the current commissioning status of DMRadio-50L, focusing on the performance of the toroidal magnet, lumped-element resonator, and dc SQUID...

The axion is a well-motivated dark matter candidate with a possible mass range spanning many orders of magnitude. Theoretical models have provided strong motivation to search for post-inflationary QCD axions, but this higher mass range is challenging to reach with traditional resonant cavity haloscopes. Among other limitations, scaling the resonant cavity to frequencies in the tens of GHz...

The MAgnetized Disk and Mirror Axion eXperiment (MADMAX) is an experiment aiming to detect dark matter axions from the galactic halo by resonant conversion to photons in a strong magnetic field. It uses a novel concept based on a stack of dielectric disks in front of a mirror, called booster, to enhance the potential signal from axion-photon conversion over a significant mass range. In its...

The axion is a particle which solves the strong CP problem and is a well-motivated candidate for dark matter. The Quantum Enhanced Particle Astrophysics (QuEPA) project at Imperial College London looks to detect axions with masses in the 124-248 µeV range (Compton frequencies 30-60 GHz). Towards this goal, a dielectric Fabry-Perot cavity has been developed to convert axions to microwave...

The search for axions has motivated a wide variety of experimental approaches exploiting the rich phenomenology of this hypothetical particle. Originally proposed as a solution to the strong CP problem in QCD, the axion is also a well-motivated dark matter candidate. The RADES collaboration aims to detect relic galactic axions using haloscopes through the Primakoff effect, whereby axions...

The search for axions, light and weakly interacting dark matter particles, is nowadays mostly exploited through photon coupling in the sub-meV region. In this range, only haloscopes have a sensitivity to test theoretically motivated axion models.
(talk by Di Vora for the [last updates on the QUAX haloscope][1])Axions can also be exploited through coupling to fermions, but no experiment is...

We propose a generic axion--driven cogenesis scenario in which both the baryon asymmetry and dark matter abundance originate from the kinetic misalignment. The framework unifies the Peccei--Quinn (PQ) mechanism with a Type--I seesaw sector, where Hubble--induced masses and higher-dimensional PQ--violating operators drive early--time axion rotation. Working within the DFSZ axion model augmented...

The QUAntum LImited PHotons In the Dark Experiment (QUALIPHIDE) is primarily a search for hidden photon dark matter. Our far-infrared variant uses an array of single O(THz) photon counting Microwave Kinetic Inductance Detectors coupled to a metallic dish. The presence of on-and-off focus pixels allows for the construction of a data-driven background model and thus results in an experiment with...

The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber 110 m away from the Booster Neutrino Beam (BNB) target at Fermilab (Illinois, USA). The close location to the BNB origin makes the experiment sensitive to physics beyond the Standard Model (BSM) produced in the beam. Thanks to its advanced scintillation light detection system, a timing resolution at the...

CUPID-0 was a pilot experiment in scintillating cryogenic calorimetry designed to search for neutrinoless double beta decay. An array of 26 ZnSe crystals coupled to bolometric light detectors was operated continuously for two years. CUPID-0 demonstrated full $\alpha$ to $\beta/\gamma$ background discrimination, set the most stringent limit on the neutrinoless double beta decay of $^{82}$Se,...

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first tonne-scale experiment using cryogenic calorimeters. The detector is located underground at the Laboratori Nazionali del Gran Sasso and consists of 988 TeO2 crystals operated in a dilution refrigerator at a base temperature of about 10 mK. Thanks to the large exposure, sharp energy resolution, segmented structure and...

ANAIS-112 is a dark matter direct detection experiment utilizing sodium-iodide scintillating crystal detectors which was mounted to search for the annual modulation signal expected from dark matter in the Galactic Halo. Located in Canfranc Underground Laboratory in Spain, the experiment has published results which are consistent with no modulation. This strategy, however, may be expanded to...

The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions and axion-like particles (ALPs) with unprecedented sensitivity. The experiment combines a dedicated superconducting dipole magnet with precision X-ray optics and ultra-low background detectors. BabyIAXO will represent the initial stage of the project, serving both as a...

X-ray telescopes have become powerful tools in the search for weakly interacting slim particles (WISPs), in particular QCD axions and axion-like particles (ALPs). Through the Primakoff effect, astrophysical magnetic fields can induce axion-photon conversion, giving X-ray observatories unique sensitivity over a broad axion-mass range. This talk reviews recent progress in ALPs searches with...

Axions and axion-like particles (ALPs) can couple to photons, and many searches have been conducted utilizing the Primakoff effect, which induces axion-photon conversion under magnetic fields. Recently, novel experiments using the interaction between axions and laser photons without magnetic fields have been proposed and are currently underway. These experiments aim to search for ALPs directly...

Axions are among the most compelling dark matter candidates, motivating the development of precision laboratory searches based on their coupling to photons. In this talk, I will discuss a polarimetric approach to axion dark matter detection using optical cavities, focusing on the birefringence induced by an oscillating axion background in laser polarization. Within this framework, axion dark...
