New limit on Lorentz and CPT violation for neutrons

Research output: Contribution to journalArticle

Abstract

We use a K-3He co-magnetometer to constrain neutron spin coupling to a Lorentz and CPT violating background field arising in many models of quantum gravity, bn<3.7×10-33 GeV, improving previous limit by a factor of 30.
