1307.6602 (E. G. Adelberger et al.)

Improved Limits on Long-Range Parity-Odd Interactions of the Neutron    [PDF]

E. G. Adelberger, T. A. Wagner
We show that a previous polarized 3He experiment at Princeton, plus Eot-Wash equivalence-principle tests, constrain exotic, long-ranged (lambda > 0.15m) parity-violating interactions of neutrons at levels well below those inferred from a recent study of the parity-violating spin-precession of neutrons transmitted through liquid 4He. For lambda > 1.0e8 meters the bounds on gAgV are improved by a 11 orders of magnitude.
