Portal Connecting Dark Photons and Axions [PDF]
, 2017 The dark photon and the axion (or axion-like particle) are popular light particles of the hidden sector. Each of them has been actively searched for through the couplings called the vector portal and the axion portal. We introduce a new portal connecting

Invisible Axions and Large-Radius Compactifications [PDF]
, 1999 We study some of the novel effects that arise when the QCD axion is placed in the ``bulk'' of large extra spacetime dimensions. First, we find that the mass of the axion can become independent of the energy scale associated with the breaking of the ...

On the 3-form formulation of axion potentials from D-brane instantons [PDF]
, 2017 The study of axion models and quantum corrections to their potential has experienced great progress by phrasing the axion potential in terms of a 3-form field eating up the 2-form field dual to the axion.

Axions and SN 1987A: Axion trapping [PDF]
Physical Review D, 1990 If an axion of mass between about 10(exp -3) eV and 1 eV exists, axion emission would have significantly affected the cooling of the nascent neutron star associated with SN 1987A. For an axion of mass less than about 10(exp -2) eV, axions produced deep inside the neutron star simply stream out; in a previous paper this case has been addressed ...

Stochastic axion dark matter in axion landscape [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We study the stochastic axion dark matter scenario in the axion landscape, where one of the axions is light and stable and therefore explains dark matter. If the axion mass at the potential is a typical value of the curvature along the direction, the potential can be well approximated by a quadratic mass term.

Josephson Junctions as Single Microwave Photon Counters: Simulation and Characterization
Instruments, 2021 Detection of light dark matter, such as axion-like particles, puts stringent requirements on the efficiency and dark-count rates of microwave-photon detectors.

Spectrum of radiation from axion strings [PDF]
, 1998 In the wide variety of axion cosmologies in which axion strings form, their radiative decay is the dominant mechanism for the production of axions, imposing a tight constraint on the axion mass.

Axions and axion-like particles [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 I review the theoretical motivation for the axion and present an update of the experimental status of axion searches. I finally comment on some aspects of the physics of axion-like particles.

Phenomenology of the companion-axion model: photon couplings
European Physical Journal C: Particles and Fields, 2022 We study the phenomenology of the ‘companion-axion model’ consisting of two coupled QCD axions. The second axion is required to rescue the Peccei–Quinn solution to the strong-CP problem from the effects of colored gravitational instantons. We investigate

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.
