[Propriétés du boson de Higgs dans le Modèle Standard et ses extensions supersymétriques]
Nous examinons le mécanisme de Brout–Englert–Higgs et décrivons les limites expérimentales et théoriques de la masse de l'unique boson de Higgs attendu dans le Modèle Standard minimal. Nous discutons également les couplages de ce boson de Higgs et ses modes de désintégration en fonction de sa masse inconnue. Nous examinons ensuite la structure du secteur de Higgs dans l'extension supersymétrique minimale du Modèle Standard (MSSM), en soulignant l'importance des corrections induites par les boucles aux masses de ses cinq bosons de Higgs physiques. Enfin, nous examinons quelques modèles non-minimaux.
We review the realization of the Brout–Englert–Higgs mechanism in the electroweak theory and describe the experimental and theoretical constraints on the mass of the single Higgs boson expected in the minimal Standard Model. We also discuss the couplings of this Higgs boson and its possible decay modes as functions of its unknown mass. We then review the structure of the Higgs sector in the minimal supersymmetric extension of the Standard Model (MSSM), noting the importance of loop corrections to the masses of its five physical Higgs bosons. Finally, we discuss some non-minimal models.
