Constraining Exotic Weakly Coupled Long-Range Interactions with Pseudoscalar and Axial Couplings with Unpolarized Data

摘要

Present laboratory limits on the strength of possible weakly coupled, long-range exotic interactions with (spin-dependent) pseudoscalar and axial couplings are many orders of magnitude weaker than their scalar and vector analogues. Here we present two physical mechanisms involving spin-dependent couplings which lead to spin-independent interactions between atoms and whose analysis should lead to improved limits.
