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.

Curl up with a good B: detecting ultralight dark matter with differential magnetometry

Journal of High Energy Physics
Ultralight dark matter (such as kinetically mixed dark-photon dark matter or axionlike dark matter) can source an oscillating magnetic-field signal at the Earth’s surface, which can be measured by a synchronized array of ground-based magnetometers.

Heavy photophobic ALP at the LHC

Journal of High Energy Physics
We study the photophobic ALP model in high-mass regions under LHC Run-II. Since the ALP is predominantly coupled with electroweak gauge bosons such as ZZ, WW, and Zγ, and less with di-photon, the model may be probed via multi-boson final-state processes.

Indirect detection of hot dark matter

Journal of High Energy Physics
Cosmologically stable, light particles that came into thermal contact with the Standard Model in the early universe may persist today as a form of hot dark matter.

A Kinetic Theory of Axions in Magnetized Plasmas: the Axionon

, 2018
We present an analytic study of the dispersion relation for an isotropic, non-degenerate plasma interacting with an axion-like particle through the axion-photon coupling. We aim to provide a general qualitative picture of the electromagnetic oscillations

Light-Shining-through-a-Wall : searching for Axion-Like Particles with the OSQAR and ALPS II experiment

, 2018
The existence of Axion-Like Particles (ALPs) is predicted by many extensions the Standard Model of particle physics. Depending on their particular properties, these particles might contribute to several so far unresolved questions of physics, such as the nature of dark matter or the anomalous cooling processes observed in stellar systems.

Solving the strong CP problem with massless grand-color quarks

Journal of High Energy Physics
We propose a solution to the strong CP problem that specifically relies on massless quarks and has no light axion. The QCD color group SU(3) c is embedded into a larger, simple gauge group (grand-color) where one of the massless, colored fermions enjoys ...
