Low-energy supernova constraints on lepton flavor violating axions

Journal of High Energy Physics
The extreme conditions within the supernova core, a high-temperature and high-density environment, create an ideal laboratory for the search for new physics beyond the Standard Model.

Sensitivity of the FCC-ee to decay of an axion-like particle into two photons

Journal of High Energy Physics
The decay of the Z boson into axion-like particles (ALP) at the Z-pole run of the proposed CERN FCC-ee collider is investigated. We perform a detailed study of final states with three photons or with a single photon and missing energy, yielding an ...

Interplay of ALP couplings at a muon collider

Journal of High Energy Physics
Axion-like particles can couple to Standard Model gluons, electroweak gauge bosons, and massive fermions. A future multi-TeV muon collider provides a favorable environment to probe axion-like particles through multiple production channels, including ...

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 ...

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.
