Abstract

We present a search for possible spin dependent interactions of the neutron with matter through exchange of spin 1 bosons with axial vector couplings as envisioned in possible extensions of the Standard Model. This was sought using a slow neutron polarimeter that passed transversely polarized slow neutrons by unpolarized slabs of material arranged so that interactions would tilt the plane of polarization and develop a component along the neutron momentum. The result for the rotation angle, ϕ^′=[2.8±4.6(stat.)±4.0(sys.)]×10⁻⁵ rad/m is consistent with zero. This result improves the upper bounds on the neutron-matter coupling g_A ² by about three orders of magnitude for force ranges in the mm– μm regime.
