Riassunto
In this thesis we present different clues of Lepton Flavour Universality violation coming from the measurements of different observables involving B mesons, known as B-Physics Anomalies.
Once we have seen the main features of these phenomena, we implement an Effective Field Theory to see what contributions to the B meson decays, which exhibit the anomalies mentioned above, are needed to fill the discrepancy with the Standard Model.
Then, we look for the proper type of new heavy particles that would generate the mentioned contributions through a tree level matching.
The final result is a list of some simplified models that would accommodate the B-Physics Anomalies by means of the inclusion of one or more heavy bosons in the theory.
