Abstract

Lorentz and CPT symmetry has been tested using a K-3He co-magnetometer which is sensitive to anomalous fields that couple to electron and nuclear spins differently than a normal magnetic field. Preliminary results obtained from data over the course of 15 months provide upper limits on the coupling energy of a CPT-violating field to neutron spin, bn < 1.4 × 10-31 GeV, to proton spin, bp < 2.2 × 10-30 GeV, and to electron spin, be < 1.0 × 10-28 GeV.
