arXiv:1809.06229 · doi:10.1088/1361-6471/aaf5de
Abstract
Several measurements of tree- and loop-level b-hadron decays performed in the recent years hint at a possible violation of Lepton Universality. This article presents an experimental and theoretical overview of the current status of the field.
