Searches for permanent electric dipole moments of particles, nuclei, atoms and molecules offer an extraordinary discovery potential to new mechanisms of CP violation beyond those incorporated in the standard electroweak model. The electric dipole moments induced by speculative scenarios, on different physical systems, require a complementary approach to pave the way to the fundamental CP-violating mechanisms. New avenues presently being explored in order to improve the experimental sensitivities include projects that consider the trapping of neutral particles, the confinement of charged particles in storage rings as well as the use of radioactive nuclei.
La recherche de moments dipolaires électriques de particules, noyaux, atomes et molecules offre un potentiel extraordinaire de découverte de nouveaux mécanismes de violation de CP autres que ceux inclus dans le modèle standard électrofaible. Les moments dipolaires électriques induits par des scénarios spéculatifs, sur divers systèmes physiques, exigent une approche complémentaire afin dʼouvrir la voie vers les mécanismes fondamentaux de violation de CP. Les nouveaux chantiers explorés actuellement afin dʼaméliorer les sensibilités expérimentales incluent des projets qui considèrent le piègeage de particules neutres, le confinement de particules chargées dans des anneaux de stockage ainsi que lʼutilisation de noyaux radioactifs.
