Probing sub-eV particles with polarized Helium 3
  Proceeding of the "Journ\'{e}es de Rencontre Jeunes Chercheurs" 2013. Measuring the depolarization rate of a $^3$He hyperpolarized gas is a sensitive method to probe hypothetical short-range spin-dependent forces. A dedicated experiment is being set up at the Institute Laue Langevin in Grenoble to improve the sensitivity. The status of the experiment is detailed in this paper.
