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, b^p < 2.2 × 10^-30 GeV, and to electron spin, b^e < 1.0 × 10^-28 GeV.
