Bounds on heavy axions with an X-ray free electron laser
Jack W. D. Halliday, Giacomo Marocco, Konstantin A. Beyer +18
We present new exclusion bounds obtained at the European X-ray Free Electron Laser facility (EuXFEL) on axion-like particles (ALPs) in the mass range 10^{-3} eV < m_a < 10^4 eV. Ou…
Blast from the past II: Constraints on heavy neutral leptons from the BEBC WA66 beam dump experiment
Ryan Barouki, Giacomo Marocco, Subir Sarkar
We revisit the search for heavy neutral leptons with the Big European Bubble Chamber in the 1982 proton beam dump experiment at CERN, focussing on those heavier than the kaon and m…
Light-shining-through-wall axion detection experiments with a stimulating laser
K. A. Beyer, G. Marocco, R. Bingham +1
The collision of two real photons can result in the emission of axions. We investigate the performance of a modified light-shining-through-wall (LSW) axion search aiming to overcom…
Parametric co-linear axion photon instability
K. A. Beyer, G. Marocco, C. Danson +2
Axions and axion-like particles generically couple to QED via the axion-photon-photon interaction. This leads to a modification of Maxwell's equations known in the literature as ax…
Blast from the past: Constraints on the dark sector from the BEBC WA66 beam dump experiment
Giacomo Marocco, Subir Sarkar
We derive limits on millicharged dark states, as well as particles with electric or magnetic dipole moments, from the number of observed forward electron scattering events at the B…
Axion detection through resonant photon-photon collisions
K. A. Beyer, G. Marocco, R. Bingham +1
We investigate the prospect of an alternative laboratory-based search for the coupling of axions and axion-like particles to photons. Here, the collision of two laser beams resonan…
