Investigating the interplay between axions and dark photons in the early universe
Axions and dark photons are two of the most promising types of particles for unveiling new physics. The axion scalar field explains the absence of an electric dipole moment for the neutron, while the dark photon resembles ...
ATLAS Experiment measures light scattering on light and constrains axion-like particles
Light-by-light scattering is a rare phenomenon in which two photons—particles of light—interact, producing another pair of photons. Direct observation of this process at high energy had proven elusive for decades, until ...
