Precision experiments with muons and neutrons
Comptes Rendus. Physique, Volume 21 (2020) no. 1, pp. 121-134.

The precision experiments with muons and neutrons are described. The topics selected cover the anomalies of the muon g μ -2 and the neutron lifetime, and searches for charged lepton flavour violation CLFV of μ - e - transition and the neutron electric dipole moment (EDM). These physics programs are anticipating significant improvements of experimental sensitivities, by a factor of ten to more than 10,000 with novel ideas and methods. They would provide a unique discovery potential to new physics beyond the Standard Model of particle physics, and is complementary to the collider and neutrino physics programs.

Une sélection d’expériences de précision employant des muons ou des neutrons sont décrites. Cette sélection couvre les anomalies dans les mesures du facteur g μ -2 du muon et de la duré de vie du neutron, ainsi que les recherches de violation de saveur pour les leptons chargés (CLFV) des transitions μ - e - et du moment dipolaire électrique (EDM) du neutron. Ces programmes promettent des améliorations significatives de la sensibilité expérimentale, les facteurs d’améliorations sont compris entre 10 et 10,000, avec des nouvelles idées et méthodes. Le potentiel de découverte de nouvelle physique au-delà du Modèle Standard de la physique des particules est complémentaire aux recherches sur collisionneurs et aux programmes avec les neutrinos.
