Physical signatures of fermion-coupled axion dark matter

Journal of High Energy Physics
In the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these effects and find that magnetized analogs of multilayer dielectric haloscopes can explore ...

Probing the gauge-boson couplings of axion-like particle at the LHC and high-luminosity LHC

Journal of High Energy Physics
In this work, we calculate the sensitivities on the gauge-boson couplings g aZZ , g aZγ , and g aWW of an axion-like particle (ALP) that one can achieve at the LHC with s $$ \sqrt{s} $$ = 14 TeV and integrated luminosities of 300 fb−1 (current run) and ...

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.

Laser-assisted Light-by-light scattering in Born-Infeld and axion-like particle theories

Journal of High Energy Physics
The precision measurements of well-known light-by-light reactions lead to important insights of nonlinear quantum electrodynamics (QED) vacuum polarization.

Searching for exotic scalars at fusion reactors

Journal of High Energy Physics
Part of the energy created in deuterium-tritium fusion reactors is carried away from plasma by a high-intensity neutron flux, which is then absorbed by the reactor’s inner walls.

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.

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 ...
