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

摘要

We show that a previous polarized 3He experiment at Princeton, plus Eot-Washequivalence-principle tests, constrain exotic, long-ranged (lambda > 0.15m)parity-violating interactions of neutrons at levels well below those inferredfrom a recent study of the parity-violating spin-precession of neutronstransmitted through liquid 4He. For lambda > 1.0e8 meters the bounds on gAgVare improved by a 11 orders of magnitude.
