The possibility for Lorentz/CPT-breaking, which is motivated by unification theories, can be systematically tested within the standard-model extension framework. In pure gravity sector, mass dimension 5 operators produce new Lorentz and CPT-breaking terms in 2-body equations of motion that depend on relative velocity bodies. this Letter, we report constraints 15 independent SME coefficients Lorentz/CPT-violations with using lunar laser ranging. We perform a global analysis ranging data framework more than 26,000 normal points between 1969 2018. also jackknife order to provide realistic estimates systematic uncertainties. No deviation from Lorentz/CPT symmetries reported. addition, when fitting simultaneously canonical Lorentz/CPT-violations, improve up three orders magnitude previous post-fit radio pulsars.
