[Désintégrations rares des hadrons beaux]
Comptes Rendus. Physique, Volume 21 (2020) no. 1, pp. 93-106.

Les désintégrations rares des hadrons beaux fournissent un environnement riche pour rechercher des effets de physique au-delà du Modèle Standard grâce à de nombreuses observables. Dans les dernières années, plusieurs tensions avec les prédictions du Modèle Standard sont apparues. Une revue des résultats expérimentaux les plus importants est présentée ainsi que leur interprétation dans le contexte de l’approche d’Hamiltonien effectif.

Rare b-hadron decays provide a rich environment to search for beyond Standard Model physics effects thanks to numerous observables. In the recent years, several tensions with the SM expectations have appeared. A review of the most important experimental results is presented together with their interpretation in the context of the effective Hamiltonian approach.
