Deuteron EDM
Permanent electric dipole moments (EDMs) violate parity and time-reversal
symmetry, and are therefore practically zero in the Standard Model (SM). Many
extensions of the SM predict much larger EDMs, which are therefore an
excellent probe for the existence of new physics. Until recently it was
believed that only electrically neutral systems could be used for a sensitive
search for EDMs. The search on charged systems has become feasible with the
introduction of a novel experimental method. This method makes use of the
strong motional electric fields that a moving charged particle experiences in
a magnetic field. It provides direct access to the very interesting realm of
light nuclei and other charged particles, which so far has not been examined
for EDMs, in particular the proton and the deuteron. The KVI focus is mainly
on the design of a highly sensitive deuteron polarimeter and corresponding
readout system.
