B decay anomalies at LHCb
The LHCb collaboration has provided a plethora of precise measurements of flavour observables in the last years. In the B sector some of these results show consistent deviations from the Standard Model with a clear tendency to specific New Physics scenarios. B decay anomalies are found in particular related to lepton flavour universality and angular observables in flavour-changing-neutral-current transitions. Results from Lattice are crucial in the coming years to verify if these anomalies are explained by QCD effects or if they are unambiguous hints of New Physics.
