Axionic dark matter signatures in various halo models

Nuclear Physics B, 2017
In the present work we study possible signatures in the Axion Dark Matter searches. We focus on the dependence of the expected width in resonant cavities for various popular halo models, leading to standard velocity distributions, e.g. Maxwell–Boltzmann,

The Tokyo Axion Helioscope Experiment [PDF]

, 1998
A preliminary result of the solar axion search experiment at the University of Tokyo is presented. We searched for axions which could be produced in the solar core by exploiting the axion helioscope.

Dark matter axion search using a Josephson Traveling wave parametric amplifier. [PDF]

Review of Scientific Instruments, 2021
We describe the first implementation of a Josephson Traveling Wave Parametric Amplifier (JTWPA) in an axion dark matter search. The operation of the JTWPA for a period of about two weeks achieved sensitivity to axion-like particle dark matter with axion ...

Quark flavor phenomenology of the QCD axion [PDF]

, 2020
Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments.

Search for energetic cosmic axions utilizing terrestrial/celestial magnetic fields [PDF]

, 1998
Orbiting $\gamma$-detectors combined with the magnetic field of the Earth or the Sun can work parasitically as cosmic axion telescopes. The relatively short field lengths allow the axion-to-photon conversion to be coherent for $m_{axion} \sim 10^{-4}$ eV,

Reheating-induced axion dark matter after low scale inflation

Journal of High Energy Physics, 2020
A kinetic mixing between the axion and the inflaton allows for a production of axion dark matter even if the inflationary Hubble scale is smaller than the zero-temperature axion mass.

Axions - Motivation, limits and searches [PDF]

, 2006
The axion solution of the strong CP problem provides a number of possible windows to physics beyond the standard model, notably in the form of searches for solar axions and for galactic axion dark matter, but in a broader context also inspires searches ...

Axion Dark Matter Search around 6.7  μeV. [PDF]

Physical Review Letters, 2020
An axion dark matter search with the CAPP-8TB haloscope is reported. Our results are sensitive to axion-photon coupling g_{aγγ} down to the QCD axion band over the axion mass range between 6.62 and 6.82  μeV at a 90% confidence level, which is the most ...
