Tidal streams from axion miniclusters and direct axion searches

, 2015
In some axion dark matter models a dominant fraction of axions resides in dense small-scale substructures, axion miniclusters. A fraction of these substructures is disrupted and forms tidal streams where the axion density may still be an order of ...

Axion strings from string axions [PDF]

Physical Review D
A favored scenario for axions to be dark matter is for them to form a cosmic string network that subsequently decays, allowing for a tight link between the axion mass and relic abundance. We discuss an example in which the axion is protected from quantum gravity effects that would spoil its ability to solve the strong CP problem: namely, a string ...

On the impact of heavy meson production spectra on searches for heavy neutral leptons

Journal of High Energy Physics
Feebly Interacting Particles are a commonly considered extension to the Standard Model of Particle Physics. In many theoretical frameworks these particles can explain observed physical phenomena which are in tension with the current model.

Effects of initial axion production and photon--axion oscillation on type Ia supernova dimming

, 2002
Recently, Csaki, Kaloper and Terning (CKT) suggested that axion-photon oscillation in the intergalactic medium can explain the observed dimming of distant type Ia supernovae.

Progress in GrAHal-CAPP/DMAG for Axion Dark Matter Search in the 1–3 μeV Range

Physical Sciences Forum
Two outstanding problems of particle physics and cosmology, namely the strong-CP problem and the nature of dark matter, can be solved with the discovery of a single new particle, the axion.

Axion stars in MGD background

European Physical Journal C: Particles and Fields, 2023
The minimal geometric deformation (MGD) paradigm is here employed to survey axion stars on fluid branes. The finite value of the brane tension provides beyond-general relativity corrections to the density, compactness, radius, and asymptotic limit of the

Renormalization Flow of Axion Electrodynamics

, 2012
We study the renormalization flow of axion electrodynamics, concentrating on the non-perturbative running of the axion-photon coupling and the mass of the axion (like) particle.

Axions and stars [PDF]

Physical Review D, 1987
The emission of light, noninteracting particles, such as axions and Majorons, modifies the structure and evolution of stars. We show that the main effects of such an energy loss are to raise the central temperature and luminosity of stars and to reduce their lifetimes.
