Abstract |
Rare decays of B mesons present a unique opportunity to probe the
consistency of the Standard Model, and in particular the universality
of the electroweak force with respect to the lepton flavour, also
known as Lepton Flavour Universality (LFU). Recent measurements of
the LHCb experiment on various B-decay measurements display persistent
deviations with respect to the Standard Model. These anomalies are
observed in absolute measurements of branching ratios, angular
observables and in tests of LFU. The
aforementioned observations, while still not at the discovery level,
suggest that a sizeable Violation of Lepton Universality (LUV) arising
from new physics might be present in nature. In this talk, recent
LHCb measurements on rare B-meson decays, with a particular focus on
tests of Lepton Flavour Universality, are reported.
