Searches for heavy QCD axions via dimuon final states

open access: yesJournal of High Energy Physics, 2023
Heavy QCD axions are well-motivated extensions of the QCD axion that address the quality problem while still solving the strong CP problem. Owing to the gluon coupling, critical for solving the strong CP problem, these axions can be produced in ...

First sensitivity limits of the ALPS TES detector

open access: yes, 2014
The Any Light Particle Search II (ALPS II) requires a sensitive detection of 1064 nm photons. Thus, a low dark count rate (DC) and a high detection efficiency (DE) is needed. ALPS has set up a transition-edge sensor (TES) detector system, namely the ALPS

Impact of Axions on the Minimum Mass of Core Collapse Supernova Progenitors [PDF]

open access: yes, 2017
In this study we include axions in stellar evolution models adopting the current stringest constraints for their coupling to photons and electrons. We obtain that the minimum stellar mass of Core Collapse Supernova (CCSN) progenitors is shifted up by ...

New Observables for Direct Detection of Axion Dark Matter

open access: yes, 2013
We propose new signals for the direct detection of ultralight dark matter such as the axion. Axion or axion like particle (ALP) dark matter may be thought of as a background, classical field.

Axions - Motivation, limits and searches [PDF]

open access: yes, 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 ...

The axion-photon mixing in non-linear electrodynamic scenarios

open access: yesJournal of High Energy Physics, 2022
In this contribution, we re-assess some aspects of axionic electrodynamics by coupling non-linear electromagnetic effects to axion physics. We present a number of motivations to justify the coupling of the axion to the photon in terms of a general non ...

Energetic axion-like particle production in galaxies

open access: yes, 2011
Relativistic axion-like particles (ALPs) originating from the stellar interiors, along with the ones coming from photon-ALP mixing in the galactic magnetic fields, contribute together to make an energetic component of the ALP content of the universe ...

Detecting the Stimulated Decay of Axions at Radio Frequencies [PDF]

open access: yes, 2019
Assuming axion-like particles account for the entirety of the dark matter in the Universe, we study the possibility of detecting their decay into photons at radio frequencies. We discuss different astrophysical targets, such as dwarf spheroidal galaxies,

Axions, their Relatives and Prospects for the Future

open access: yes, 2007
The observation of a non-vanishing rotation of linear polarized laser light after passage through a strong magnetic field by the PVLAS collaboration has renewed the interest in light particles coupled to photons.

Flavor constraints on electroweak ALP couplings [PDF]

open access: yes, 2019
We explore the signals of axion-like particles (ALPs) in flavor-changing neutral current (FCNC) processes. The most general effective linear Lagrangian for ALP couplings to the electroweak bosonic sector is considered, and its contribution to FCNC decays
