New limits on Anomalous Spin-Spin Interactions

New limits on Anomalous Spin-Spin Interactions

We report the results of a new search for long range spin-dependent interactions using a Rb -\(^{21}\)Ne atomic comagnetometer and a rotatable electron spin source based on a SmCo\(_{5}\) magnet with an iron flux return. By looking for signal correlations with the orientation of the spin source we s...

Zusammenfassung:We report the results of a new search for long range spin-dependent interactions using a Rb -\(^{21}\)Ne atomic comagnetometer and a rotatable electron spin source based on a SmCo\(_{5}\) magnet with an iron flux return. By looking for signal correlations with the orientation of the spin source we set new constrains on the product of the pseudoscalar electron and neutron couplings \(g^e_p g^n_p/\hbar c
