LOW-ENERGY TESTS OF LORENTZ SYMMETRY: NEW CONSTRAINTS WITH NUCLEONS IN A COLD ATOM CLOCK
Résumé
We report on a Lorentz invariance test with nucleons in a cold atom 133 Cs clock
using spin-polarized states. We analyze this test in the Standard Model
Extension framework, and improve by up to 13 orders of magnitude the constraints
on some coefficients parametrizing Lorentz violations.
