Photon conversion to axions and dark photons in magnetized plasmas: a finite-temperature field theory approach

Journal of High Energy Physics
Some of the most stringent constraints on physics beyond the Standard Model (BSM) arise from considerations of particle emission from astrophysical plasmas.

Refined low-energy supernova constraints on lepton flavor violating axions

Journal of High Energy Physics
The supernova (SN) core, characterized by its extreme temperature and density, serves as a unique laboratory for new-physics searches. Low-energy supernovae (LESNe) provide particularly powerful probes, as their low explosion energies place stringent ...

Multiple axions in laboratory experiments

Journal of High Energy Physics
Axions and axion-like particles generically appear in extensions of the Standard Model. While many searches assume only a single axion species, there may exist a whole spectrum of multiple such fields.

K ± → π ±a at next-to-leading order in chiral perturbation theory and updated bounds on ALP couplings

Journal of High Energy Physics
The weak decays K ± → π ± a offer a powerful probe of axion-like particles (ALPs). In this work, we provide a comprehensive analysis of these processes within chiral perturbation theory, extending existing calculations by including complete next-to ...

Probing QCD Axions or axion-like particles in three-body K decays

Journal of High Energy Physics
Two-body decays like K → πa rank among the most constraining collider probes for new, low-mass, feebly interacting pseudoscalar particles a. We explore an alternative class of kaon decay modes, specifically three-body decays to ππa or μμa.

From supernovae to neutron stars: a systematic approach to axion production at finite density

Journal of High Energy Physics
We present a systematic study of QCD axion production in environments with finite baryon density and temperature, implying significant changes to axion phenomenology.
