   Abstract:
   Various theories predict the possible existence of T-odd and P-odd shortrange forces between spin 1/2 fermions, proportional to S· r where S is the fermion spin and r is the separation between particles. We use ensembles of polarized nuclei and an un-polarized mass to search for such a force over sub-mm ranges. We established an improved upper bound on the product g sgpⁿ of the scalar coupling to particles in the un-polarized mass and the pseudo-scalar coupling of polarized neutrons for force ranges from 10^-4 to 10^-2 m, corresponding to a mass range of 2· 10^-3 to 2· 10^-5 eV for the exchange boson [1]. © Owned by the authors, published by EDP Sciences, 2014.
