The OSQAR photon regeneration experiment searches for pseudoscalar and scalar axion-like particles by the method of "Light Shining Through a Wall", based on the assumption that these weakly interacting sub-eV particles couple to two photons to give rise to quantum oscillations with optical photons in strong magnetic field. No excess of events has been observed, which constrains the di-photon coupling strength of both pseudoscalar and scalar particles down to $5.7 \cdot 10^{-8}$ GeV$^{-1}$ in the massless limit. [...]

Results and Perspectives for Laboratory Search of Weakly Interacting Sub-eV Particles with the OSQAR Experiment
/ OSQAR Collaboration
Recent intensive theoretical and experimental studies highlight the possibility of new fundamental particle physics beyond the standard model that can be probed by sub-eV energy experiments. The OSQAR photon regeneration experiment looks for Light Shining through a Wall (LSW) from the quantum oscillation of optical photons into Weakly Interacting Sub-eV Particles (WISPs), like axion or axion-like particles (ALPs), in a 9 T transverse magnetic field over the unprecedented length of 2 x 14.3 m.

Results from the OSQAR photon-regeneration experiment : No light shining through a wall
/ OSQAR Collaboration
A new method to amplify the photon-axion conversions in magnetic field is proposed using a buffer gas at a specific pressure. As a first result, new bounds for mass and coupling constant for purely laboratory experiments aiming to detect any hypothetical scalars and pseudo-scalars which can couple to photons were obtained at 95% confidence level, excluding the PVLAS result newly disclaimed..

Feasibility Study of an Experiment to Measure the Vacuum Magnetic Birefringence
/ Pugnat, P ; Duvillaret, L ; Finger, Miroslav H ; Kral, M ; Siemko, A ; Zicha, J
The use of a recently decommissioned 15-meters long twin aperture LHC superconducting magnet prototype having a transverse magnetic field B ~ 9.5 T provides the unique opportunity for the construction of a new powerful experiment to measure the Vacuum Magnetic Birefringence (VMB). The values or the limit values of the mass and of the coupling constant to two photons of possible dark matter candidates such as axions are aimed to be deduced from such an experiment. [...]
