Plans for the measurement of charged hadron electric dipole moments (EDMs) at storage rings will be presented. These experiments will also allow for searches of oscillating EDMs connected with axion or axion-like particles. Results of a first test run will be discussed.

We present the first constraints from a search for light scalar particles produced in association with $t\bar{t}$ and jet final states using 36 fb$^{-1}$ of data collected at $\sqrt{s}=13$ TeV with the ATLAS detector. The results are interpreted in the context of an Effective Field Theory model of scalar Dark Energy with conformal and disformal couplings. The results provide the most stringent...

EDELWEISS is a phased direct Dark Matter search program based on cryogenic high purity Ge mono-crystals. The simultaneous measurement of heat via thermal sensors (NTDs) and ionization allows for discrimination of nuclear and electron recoils. Based on electronic recoils, a search for axions and axion-like particles in the keV mass range can be performed. With an optimized setup of phonon...

Dark energy poses one of the most intriguing mysteries of our time and so far no experimental efforts could validate any of the existing theories. In 2003 the chameleon, a neutral spinless scalar particle, had been postulated as possible candidate. This particle couples to photons and can be produced in the Sun by the Primakoff effect. The CERN Axion Solar Telescope (CAST) aims to detect these...

Next generation telescopes such as the Square Kilometre Array (SKA) present an exciting opportunity for radio astronomy to contribute to the search for dark matter. Using the theory initially set out by Sikivie 1983 we investigate axion conversion in the magnetic fields that pervade spiral galaxies, galaxy clusters and around dense objects such as neutron stars. I will present the strength of...
