Search for Exotic Couplings in Neutron Decay : A Measurement of the Transverse Polarization of Electrons
Résumé
First results are presented from an experiment that aims at the simultaneous determination of both transversal polarization components of electrons emitted in the decay of free neutrons – two observables that have never before been addressed experimentally. They reveal first-order sensitivity to real and imaginary parts of the exotic scalar and tensor interactions.
