New Upper Limit on the Axion-Photon Coupling with an Extended CAST Run with a Xe-Based Micromegas Detector / CAST Collaboration
Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for solar axions via their back conversion to X-ray photons in a 9-T 10-m long magnet directed towards the Sun. [...]

Search for dark matter axions with CAST-CAPP / Adair, C.M. (British Columbia U.) ; Altenmüller, K. (Zaragoza U.) ; Anastassopoulos, V. (Patras U.) ; Cuendis, S. Arguedas (CERN) ; Baier, J.

The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has searched for axions in the 19.74 $\mu$eV to 22.47 $\mu$eV mass range. The detection concept follows the Sikivie haloscope principle, where Dark Matter axions convert into photons within a resonator immersed in a magnetic field. [...]

First results of the CAST-RADES haloscope search for axions at 34.67 $\mu$eV / CAST Collaboration
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67$\mu$eV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. [...]

First Results from Axion Haloscope at CAPP around 10.7 $\mu$eV / CAPP Collaboration
The Center for Axion and Precision Physics research at the Institute for Basic Science is searching for axion dark matter using ultra-low temperature microwave resonators. We report the exclusion of the axion mass range 10.7126$-$10.7186 $\mu$eV with near Kim-Shifman-Vainshtein-Zakharov (KSVZ) coupling sensitivity and the range 10.16$-$11.37 $\mu$eV with about 9 times larger coupling at 90$\%$ confidence level.

(IBS, Daejeon) ; Zioutas, Konstantin (Patras U.)
We investigate the prospects for direct detection of Dark Matter (DM) particles, such as dark photons, incident on the upper atmosphere. A recent work relates the burst-like temperature excursions in the stratosphere at heights of ~38-47 km with incident invisible streaming matter. [...]

We report on a first measurement with a sensitive opto-mechanical force sensor designed for the direct detection of coupling of real chameleons to matter. These dark energy candidates could be produced in the Sun and stream unimpeded to Earth. [...]

Improved Search for Solar Chameleons with a GridPix Detector at CAST / CAST Collaboration
We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200 eV to 10 keV from converted solar chameleons. [...]

Preliminary Study for a New Axion Dark-Matter Haloscope / Pugnat, P (LNCMI, Grenoble) ; Ballou, R (Neel Lab, Grenoble) ; Camus, Ph (Neel Lab, Grenoble) ; Caspers, F (ESI, Archamps ; CERN) ; Ko, B R (IBS, Daejeon) ; Roch, N (Neel Lab, Grenoble) ; Semertzidis, Y K (IBS, Daejeon ; KAIST, Taejon)
A new haloscope for Axion dark-matter search is under study using in a first step the large bore superconducting magnet in construction at the LNCMI in Grenoble, which will produce 9~T in 812~mm diameter and 1400~mm height. Microwave cavities of high quality factor $Q\sim10^5-10^6$ will be developed at CAPP/IBS in Daejeon. [...]
