Description

We report a new experimental result on searching for exotic spin- and velocity- dependent force using a tungsten nucleon source and an K-Rb-21Ne comagnetometer [1]. The pseudomagnetic field from this exotic force is measured to be ≤ 7 aT. This sets new limits on coupling constants for the neutron-nucleon and proton-nucleon interactions in the force range of ≥ 0.1 m.
