Probing Light Pseudoscalar Particles Using Synchrotron Light

Dias, A. G., Lugones, G.

Understand

The need for purely laboratory-based light pseudoscalar particles searches has been emphasized many times in the literature, since astrophysical bounds on these particles rely on several assumptions to calculate the flux produced in stellar plasmas.

  • In this paper we study the use of light from synchrotron accelerators as a source for a photon regeneration experiment also know as "light shining through a wall".
  • Such an experiment can significantly improve present limits on the pseudoscalar particle mass and the pseudoscalar-photon coupling constant obtained from laser experiments.
  • This is possible even using a small number of powerful magnets (B = 10 T), due to the large incident photon flux.
