Résumé
Les expériences modernes sur la désintégration béta du neutron ainsi que des noyaux légers fournissent des contraintes importantes sur la théorie de l'interaction faible. Ces expériences produisent des valeurs plus précises des constantes de couplage permis et induit de l'interaction faible, et permettent de contraindre les extensions possibles au "modèle standard" électro-faible.


Abstract
Modern experiments investigating the beta decay of the neutron and light nuclei are still provide important constraints on the theory of the weak interaction. Beta decay experiments are yielding more precise values for allowed and induced weak coupling constants and putting constraints on possible extensions to the standard electroweak model. Here we emphasize the implications of recent experiments to pin down the strengths of the weak vector and axial vector couplings of the nucleon.
